How to Fix a DNS Error: A Practical Guide

This article was assisted with AI. We may include links to partners.

When you run into a DNS error, the fix is often surprisingly simple. An actionable first step is to restart your device and router or just clear your browser's cache. If the problem sticks around, flushing your computer’s DNS cache or switching to a public DNS server like Google’s (8.8.8.8) usually does the trick.

What a DNS Error Means and Why It Happens

Think of the internet like a giant, global address book. When you type a website like soloist.ai into your browser, the Domain Name System (DNS) is the service that looks up its corresponding IP address—a string of numbers that servers use to find each other.

A DNS error simply means that lookup failed. Your browser asked for the website's "phone number," but for some reason, the address book couldn't find a working entry.

This is a common and usually harmless issue. It doesn’t mean your internet is down or the website has vanished. It’s just a sign of a temporary communication breakdown somewhere along the line. Figuring out why it happened is the key to fixing it fast.

Common Causes of a DNS Failure

The cause of a DNS error can be anything from a small glitch on your computer to a major outage at your internet provider. The good news is most of these issues are straightforward to diagnose and fix.

Here are the most common causes:

  • Local Device Issues: Your own computer or browser might be holding onto old, incorrect DNS information in its cache.
  • Router Problems: Your router can get overwhelmed or glitch, messing up how it handles network traffic and DNS lookups.
  • ISP Server Trouble: The DNS servers run by your Internet Service Provider (ISP) might be down, overloaded, or just having a bad day.
  • Website-Specific Problems: Sometimes, the problem isn't on your end. The website you're trying to reach could have its own incorrect DNS settings.

A DNS error is often just a temporary mismatch. It’s your browser's way of saying, "I tried to connect, but the address I was given didn't work." The solution is usually to clear out the old address and get a new one.

These errors have become more common as the internet grows. Major providers have been hit with DNS-related outages multiple times. During a memorable Zoom outage, for example, key server records vanished, making the service unreachable for businesses everywhere, even though the servers themselves were fine.

This problem is growing with 26 million new domains registered in Q2 2025 alone. With so many new sites coming online, the odds of a misconfiguration leading to an error have increased. You can check out more of these trends over at Ookla.com.

For most people, including anyone using the Solo AI Website Creator, just knowing these potential causes is half the battle. It helps you quickly figure out if the issue is with your device, your network, or the site itself before diving into more technical fixes.


Before you dig into advanced settings, a few quick checks can often resolve the problem in minutes. This table summarizes the most effective first steps.

Quick Fixes for Common DNS Errors

Troubleshooting Step What It Does Best For
Restart Device & Router Clears temporary memory and establishes a fresh connection to your ISP. The best first step for any connectivity issue.
Clear Browser Cache Deletes old, potentially corrupt website data stored by your browser. Errors that happen on one browser but not others.
Flush DNS Cache Forces your computer to forget old DNS entries and get new ones. When a website has recently changed its IP address.
Switch to Public DNS Bypasses your ISP's DNS servers, which may be slow or temporarily down. Widespread errors affecting multiple websites.

These simple actions are powerful and can often get you back online without any more effort. If the issue persists, then it’s time to look at more specific causes.

Your First Steps to Troubleshooting DNS Errors

When a DNS error stops you, it's easy to assume you're dealing with a complex network problem. But the most common causes are surprisingly simple to fix, and you can usually get everything sorted in just a few minutes right from your device.

Before you start changing network settings, let's walk through the first things you should always try. These actionable steps solve the vast majority of DNS issues.

This flowchart gives you a quick visual guide for tackling a DNS error, leading you from the simplest checks to more involved solutions if needed.

The key takeaway is that you can often fix things yourself with a few basic troubleshooting steps before you ever need to call your ISP.

Clear Out Old Data by Flushing Your DNS Cache

Think of your computer's DNS cache as a temporary address book. To speed things up, it saves the IP addresses of websites you've visited recently. The problem is, this information can become outdated or corrupted, blocking you from reaching a site even if it's working fine.

"Flushing the cache" is just a term for forcing your computer to wipe that temporary address book clean. It deletes all the old data so that the next time you visit a site, your computer has to ask for a fresh, correct address. This is almost always the best first action to try.

Here’s how to do it on your machine:

  • On Windows: Open Command Prompt as an administrator, type ipconfig /flushdns, and hit Enter.
  • On macOS: Open Terminal and run this command: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder. You'll need to enter your password.
  • On Linux: In the Terminal, type sudo systemd-resolve --flush-caches and press Enter. (Note: This command can vary slightly depending on your Linux distribution.)

Investigate Your Browser

Sometimes, the problem isn't your computer or your network—it's your web browser. Browsers keep their own separate caches to load pages faster, and just like your computer's cache, they can get stuck with old, incorrect information.

The quickest way to test this is to open a different browser. If the website loads instantly in Firefox but gives you an error in Chrome, you've found the culprit.

When that happens, the fix is to clear your browser's cache and cookies. This removes locally stored website files that might be causing the conflict. You can find this option in your browser's "Settings" or "Privacy & Security" menu.

Actionable Tip: Before you clear everything, try opening the website in an incognito or private browsing window. These modes usually ignore the browser's cache, so if the site loads there, it’s a clear sign that your cache is the problem.

The Classic Reboot: A Universal Fix

"Have you tried turning it off and on again?" is a cliché for a reason: it works.

Restarting your computer and your router is a surprisingly effective way to clear temporary glitches and memory issues that can interfere with your network connection. A reboot forces your devices to establish a completely fresh connection to your Internet Service Provider (ISP) and grab new network details, which often clears up a stubborn DNS error.

For the best results, follow this simple process:

  1. Shut down your computer completely, don't just put it to sleep.
  2. Unplug your router and modem from the wall outlet.
  3. Wait for at least 60 seconds. This gives all the internal parts a chance to fully power down and reset.
  4. Plug the modem back in first. Wait for its lights to go solid (usually green), indicating it's fully online.
  5. Now, plug the router back in and give it a minute or two to boot up.
  6. Finally, turn your computer back on and try visiting the website again.

If these initial steps don't solve the problem, especially for those working remotely, getting help from a professional remote IT support service can be a great next step. For most of us at home, these three checks are all it takes to get back online.

Using a Public DNS Resolver to Fix Persistent Errors

If you’ve restarted your devices and flushed your DNS cache but the DNS error won't go away, the problem is often the default DNS server provided by your Internet Service Provider (ISP).

Think of your ISP's DNS as the local phone book for the internet—it’s usually fine, but it can be slow, out of date, or even go offline. When that happens, your browser’s requests for website addresses go nowhere.

The good news is you can easily switch to a public DNS resolver. This is like swapping that local phone book for a massive, globally-updated library that’s almost always faster and more reliable.

Making this one simple change is a powerful fix. It lets you bypass your ISP’s potentially unreliable system and take back control of your internet connection.

Why Switch to a Public DNS?

The biggest reason is reliability. Public DNS providers like Google and Cloudflare run massive, resilient global networks built to handle huge amounts of traffic. While your local ISP's servers might struggle, these networks are almost always up and running.

We see this during major internet outages. Take the Partner Communications failure on December 30, 2025, for example. As their traffic dropped, queries to public resolvers like Cloudflare's 1.1.1.1 shot up dramatically. As detailed on the DNSimple blog, savvy users know to switch to a public DNS the moment their ISP’s system starts to fail.

But fixing errors isn't the only perk. Switching often brings other benefits:

  • Faster Browsing: Many public DNS servers are significantly faster than ISP defaults, which can make websites load quicker.
  • Better Security: Some resolvers automatically block phishing sites and other malicious content, adding a free layer of protection.
  • More Privacy: Some providers are built with a privacy-first mindset, promising not to log or sell your browsing data.

Popular Public DNS Resolvers Compared

Choosing a public DNS resolver is easy, as a few big names stand out for performance and features. Here’s a quick comparison to help you pick the right one.

Provider Primary DNS Secondary DNS Key Feature
Cloudflare 1.1.1.1 1.0.0.1 Privacy-focused and often the fastest performance.
Google 8.8.8.8 8.8.4.4 Extremely reliable and widely trusted.
Quad9 9.9.9.9 149.112.112.112 Blocks malicious domains for enhanced security.
OpenDNS 208.67.222.222 208.67.220.220 Offers customizable family-safe content filtering.

Any of these are a fantastic upgrade from your standard ISP resolver. Just pick one that aligns with your priorities, whether that's speed, security, or privacy.

How to Change Your DNS Settings on Windows

Swapping your DNS server on a Windows PC is easy and only takes a couple of minutes. Just follow these steps.

  1. First, open the Control Panel. You can search for it in the Start Menu.
  2. Go to "Network and Internet," then click "Network and Sharing Center."
  3. On the left-hand side, click "Change adapter settings."
  4. Right-click on your active internet connection—it’ll likely be called "Wi-Fi" or "Ethernet"—and choose "Properties."
  5. In the list, find and select "Internet Protocol Version 4 (TCP/IPv4)" and click the "Properties" button.
  6. Click the bubble next to "Use the following DNS server addresses."
  7. Type in the new addresses. For Google DNS, you’d put 8.8.8.8 in the "Preferred" box and 8.8.4.4 in the "Alternate" one.
  8. Click "OK" to save everything. Restart your browser to make sure the change takes effect.

Actionable Tip: Remember to flush your DNS cache one last time after making this change. This forces your system to start fresh and clear out any old, cached data from your previous DNS settings.

How to Change Your DNS Settings on macOS

For Mac users, the process is just as simple. The menus look different, but the goal is the same: swapping out the DNS server addresses.

  1. Open System Settings (or System Preferences on older macOS versions) from the Apple menu.
  2. Click on the "Network" icon.
  3. Select your active connection (Wi-Fi or Ethernet) from the list on the left, then click the "Details…" or "Advanced…" button.
  4. Go to the "DNS" tab.
  5. Click the small + button under the "DNS Servers" box to add a new one.
  6. Type in the primary address for your chosen resolver (like 1.1.1.1 for Cloudflare).
  7. Click + again and add the secondary address (like 1.0.0.1).
  8. Click "OK" and then "Apply" to save your new settings.

That’s it! You've just told your computer to bypass your ISP's DNS and use a more robust, global system. This single tweak can solve many stubborn "how to fix a DNS error" problems.

Troubleshooting DNS Errors for Your Solo AI Website Creator Site

There's nothing more frustrating than launching your brand-new website, built with Solo AI Website Creator, only to be met with a DNS error. Don't panic. This is a common issue, and it almost always comes down to a simple step in the domain connection process.

The usual causes are either incorrect nameserver settings or the natural delay while your new domain information travels across the internet. Let's walk through how to check everything and get your site live.

A hand points at a laptop screen displaying DNS registration and domain management settings.

Verifying Your Domain Nameservers

Nameservers act as the forwarding address for your website. When someone types yourdomain.com, their browser first asks your domain registrar (like GoDaddy or Namecheap) for directions. The nameservers you enter there must point straight to Solo AI Website Creator's servers.

If that forwarding address is wrong, browsers get lost, and you get a DNS error.

To fix this, log into your domain registrar's account and find the DNS or nameserver management area. You’ll need to replace any existing nameservers with the specific ones Solo AI Website Creator gave you. Copy and paste them exactly as provided to avoid typos.

Understanding DNS Propagation

Once you’ve updated your nameservers, the changes aren't instant. This is where a concept called DNS propagation comes in.

Imagine you sent out a mass text with a new address. It takes time for that message to reach everyone and for them to update their contact list. DNS works the same way. It can take up to 48 hours (though it's often just 4-6 hours) for internet providers globally to update their records with your site's new "address."

During this waiting period, your site might work for you but not for someone else. This is confusing, but it's totally normal.

Actionable Tip: The most common "fix" for a DNS error on a new domain is to wait. Give it a solid 24 hours for the new nameserver information to spread before worrying that something is broken.

Checking Your Essential DNS Records

Beyond nameservers, your domain needs two key records to work properly: the A record and the CNAME record. The good news? For most Solo AI Website Creator users, the platform handles these for you once your nameservers are pointed correctly. But if you’re managing your DNS manually, you'll want to double-check them.

Here’s what they do:

  • A Record: This points your main domain (e.g., yourwebsite.com) directly to a specific server IP address.
  • CNAME Record: This acts as an alias, usually for pointing a subdomain like www.yourwebsite.com to your main domain. It ensures people who type "www" still land on your site. For more on this, check out our guide on how to create a subdomain.

Go to your domain registrar’s dashboard and look for "DNS Management" or "Advanced DNS." You should see the records that Solo AI Website Creator requires. If you see old records from a previous web host, it's best to delete them to avoid conflicts.

For small businesses, dealing with DNS settings can be a distraction. If you're stuck, expert help from Small Business IT Consulting Services can get you back on track fast. But for most people, a careful check of nameservers, propagation time, and basic records is all it takes to solve the mystery.

What to Do When the Problem Isn't on Your Computer

You’ve tried everything. You flushed your cache, rebooted your machine, and even swapped DNS servers, but the DNS error won’t go away. This is a strong signal the problem isn't on your device. The issue might be your router, your Internet Service Provider (ISP), or even the website you're trying to reach.

Knowing how to spot these external problems can save you hours of frustration. Sometimes, the best action is to recognize the problem is out of your hands and wait for someone else to fix it.

This whole process is about elimination. By working your way from your device out to the wider internet, you can figure out exactly where the connection is broken.

Is Your Router the Bottleneck?

Before blaming your ISP, check your router. A simple reboot can do wonders, but a proper power cycle is more effective.

Unplug your router from the wall outlet and leave it for a full 60 seconds. This allows the internal memory to fully clear, wiping away any temporary glitches that could be causing the DNS issue. Plug it back in and give it a few minutes to boot up and connect to your ISP.

This single step has a high success rate. On October 22, 2025, a massive DNS failure at Fastweb caused a traffic drop of over 75%. For most people at home, the fix was just a router restart. This simple reboot got things working again for 75% of affected households, allowing their devices to reconnect to the ISP's newly restored servers.

Checking for ISP Outages

If a router reboot doesn't work, look one step further to your Internet Service Provider. ISPs run massive networks, and occasionally, things break. Their DNS servers might get overwhelmed or go down for maintenance.

The quickest way to check is to grab your smartphone (using cellular data, not your Wi-Fi). A quick search on X (formerly Twitter) or a visit to a tracker like Downdetector will tell you if others are reporting the same problem.

Here’s an actionable checklist:

  • Check the ISP's official social media: Most providers post updates on major service disruptions.
  • Visit an outage reporting website: These sites collect user reports in real-time, giving you a live view of what's happening.
  • Ask a neighbor: A quick text to someone nearby on the same ISP is a great low-tech way to confirm a local outage.

If it's a widespread issue, there's not much you can do. It's in the hands of their network engineers, and you'll have to wait it out.

Is the Website Down for Everyone?

What if the error only happens for one specific website? If you can browse the rest of the web just fine, the problem is almost certainly with the website itself, not you.

To be sure, use a free online tool like "Down for Everyone or Just Me." You just enter the website's URL, and it will check the site from multiple servers around the globe to see if it's reachable.

This is a crucial step. It stops you from wasting time troubleshooting your own network when the problem is on the other side of the world. If the site is down for everyone, the only solution is to wait for its owner to fix the issue.

The cause could be anything from an expired domain name to a server crash. Whatever the reason, the ball is in the website administrator's court. Understanding these potential points of failure is also a big part of learning how to choose a web hosting service that offers solid reliability.

Got More Questions About DNS Errors?

Even after running through common fixes, you might still have questions. DNS can be a tricky system with many interconnected parts. Let's tackle some of the most common questions to clear up any lingering confusion.

This is your quick-reference guide for those practical, "what if" scenarios.

How Long Does It Take to Fix a DNS Error?

The answer depends on the cause. A DNS fix can take anywhere from a few seconds to a couple of days.

Here’s a realistic breakdown of what to expect:

  • A few minutes: If the problem is on your device, flushing your DNS cache or restarting your router can get you back online almost instantly.
  • Nearly instant: Switching to a public DNS resolver like Google or Cloudflare is another quick win. The change takes effect as soon as you save it.
  • Up to 48 hours: This is the one that trips up new website owners, especially when using a platform like the Solo AI Website Creator. The delay is almost always due to DNS propagation. After you update your domain's nameservers, it can take up to two days for that change to spread across the entire global internet. It's often much faster, but you have to be prepared for the full window.
  • Out of your hands: If your ISP is having a major outage or a website's server has crashed, the timeline is unfortunately up to them.

Could a Virus Be Causing My DNS Error?

Yes. While less common than other issues, some malware is built specifically to interfere with your computer's DNS settings. This is often called DNS hijacking.

This malicious software intercepts your DNS requests. At best, it just blocks them. More dangerously, it can redirect you to fake websites designed to steal your login credentials or financial information.

If you’ve tried every standard troubleshooting step and the DNS errors persist, take this possibility seriously. Your next actionable step is to run a full system scan with a reputable antivirus and anti-malware program to find any hidden threats that might be hijacking your network settings.

Why Does the DNS Error Only Happen on One Website?

This is a frequent scenario and is one of the easiest to diagnose. If you can browse the rest of the internet fine but one specific site keeps giving a DNS error, the problem is almost certainly not on your end.

The issue is with that specific website's setup. A few things could be happening:

  • The server is down: The machine hosting the website might simply be offline.
  • DNS misconfiguration: The site's owners might have made an error when setting up their DNS records.
  • The domain expired: It happens more than you'd think. The website's domain name may have expired if they forgot to renew it.

Your best action is to use an online tool like "Down for Everyone or Just Me" to see if others are having the same problem. If the tool confirms the site is down for everyone, the only solution is to wait for the site’s administrators to get it back online.

Will Using a Public DNS Server Slow Down My Internet?

This is a common myth, but the reality is usually the opposite. In most cases, switching to a high-quality public DNS server will actually speed up your browsing experience. Your Internet Service Provider’s default DNS servers are often overloaded and not optimized for speed.

On the other hand, major public DNS providers like Cloudflare (1.1.1.1) and Google (8.8.8.8) have built massive, globally distributed networks designed for performance.

A faster DNS lookup means your browser gets the website's IP address more quickly. That fraction of a second saved translates to a shorter load time for every page you visit, making your internet experience feel snappier.
