A webpage that refuses to load can stop work and cause real frustration. One common message behind this problem is the “ERR_NAME_NOT_RESOLVED” error. This article explains what this error means, why it happens, and how you can fix it using clear and practical steps.
Here are the basics of the error, common causes, and proven solutions that work for most users.
What the Error Means
The “ERR_NAME_NOT_RESOLVED” error appears when your browser cannot find the IP address linked to a website name. Every website uses a domain name, but computers connect using numbers called IP addresses. A system called DNS, or Domain Name System, translates the name into the correct number.
When this translation fails, the browser does not know where to connect. As a result, the page does not load, and the error message appears. This issue usually relates to network settings, DNS problems, or browser data.
Identifying Common Causes of the Error
Several issues can trigger this error. A weak or unstable internet connection is one of the most common reasons. If your device cannot reach the DNS server, the request fails.
Incorrect DNS settings can also cause this problem. This may happen after a network change, software update, or manual configuration. In some cases, the DNS cache stored on your device becomes outdated or corrupted.
Browser-related issues can play a role as well. Cached files, cookies, or extensions may block proper DNS resolution. Security software or firewall settings may also interfere with network requests.
Checking Your Internet Connection
Start with the basics. Disconnect from your network and reconnect after a few seconds. If you use Wi-Fi, restart your router and modem. This step often clears temporary network issues.
Try opening a different website. If no sites load, the problem is likely with your internet connection. If other sites work, the issue may relate to DNS or browser settings.
Clearing the DNS Cache
Your device stores DNS data to load websites faster. Over time, this data can become incorrect. Clearing the DNS cache forces your system to request fresh information.
On Windows, open the Command Prompt as an administrator and type ipconfig /flushdns, then press Enter. On macOS, open Terminal and use the command sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder. After clearing the cache, restart your browser and try again.
Changing DNS Server Settings
Switching to a public DNS server often resolves this error. Many users choose Google DNS or Cloudflare DNS because they are reliable and fast.
You can change DNS settings through your network adapter or Wi-Fi settings. Replace the automatic DNS values with public ones and save the changes. Restart your browser after making this update.
Checking Browser Settings and Data
Sometimes the issue sits inside the browser. Clear cached images, files, and cookies. This removes stored data that may block proper site loading.
Disable browser extensions one by one and reload the page. If the site loads after disabling an extension, that extension may be the cause. Also, check if the browser is up to date, since older versions may face network issues.
Reviewing Firewall and Security Software
Firewalls and antivirus tools can block DNS requests. Temporarily disable them and test the website. If the site loads, review the software settings and allow browser access.
Do not leave security tools disabled. Adjust their rules so they allow normal network traffic without blocking DNS requests.
Knowing When the Issue Is Not on Your Side
Sometimes the problem comes from the website itself. If the site’s DNS records are down or misconfigured, you cannot fix it from your device. In such cases, waiting or contacting the website owner is the only option.
Final Thoughts
The “ERR_NAME_NOT_RESOLVED” error usually links to DNS or network problems. By checking your connection, clearing DNS data, updating DNS settings, and reviewing browser or security tools, you can resolve the issue in most cases. These steps help restore access and reduce repeat problems in the future.
