This error means that the DNS (Domain Name System, which translates website names into IP addresses) lookup failed, and the domain name does not exist in the DNS records. The most common cause of this issue is incorrect DNS configuration, either on the client side (your device) or the server side (the website’s server settings), but it can also be triggered by network issues or DNS server problems.
Basic Troubleshooting
First, verify the domain name or website URL to ensure accuracy. Attempt to access the website on another device. If successful on a different device, this indicates a misconfiguration on your main device, and you should proceed with the solutions below.If the website is not accessible on any device, it could either be that the website has restricted access from your ISP/Country or the website is down, potentially due to issues on the webmaster’s end. In such scenarios, you can only wait until the problem is resolved.
As a webmaster, check the website’s DNS settings to ensure correct configuration. If the DNS settings are not at fault, troubleshoot your hosting to solve the issue.
1. Power Cycle Your Router
For example, I encountered this error when attempting to access my router’s admin panel after prolonged router usage without a restart. Restarting the device immediately resolved the error.
2. Switch to a Public DNS
Normal DNS services map user-friendly domain names to IP addresses so browsers can understand and load the website requested. Automatic DNS servers can be unreliable; hence, we recommend using Google’s Public DNS for stability. Switch to Google DNS using the following instructions if the automatic DNS provided by your ISP is problematic.
3. Assign Automatic IP Address
When you choose Assign Automatic IP Address, your device reaches out to the DHCP (Dynamic Host Configuration Protocol) server in your network. This server automatically assigns an IP address to your device that’s in accordance with your current network settings. By doing this, you avoid potential IP conflicts or misconfigurations that might disrupt the connection between your device and the DNS server, as a result helping to resolve the error.
4. Disable Ad Blocker
Ad blockers work by blocking certain domains known for ads and unwanted content, which could sometimes result in the blocking of legitimate domains. Disabling the ad blocker allows your DNS queries to proceed unrestrained, potentially resolving the issue and restoring access to the web page you’re trying to visit.
5. Remove Website From Hosts File (if applicable)
The hosts file is like an address book for your computer, directing where it goes to find certain websites. If a specific domain is incorrectly listed there, it could cause the error by overriding DNS settings. By deleting any such entries related to the problematic domain, you essentially tell your computer to look up the address elsewhere, which can resolve the issue if the hosts file was indeed causing a blockage.
6. Disable Third-Party Antivirus
Sometimes, antivirus software can mistakenly block legitimate DNS queries as part of its protective measures. By disabling the antivirus, you remove this potential blockade, allowing your device to properly communicate with DNS servers and resolve domain names into IP addresses. Always remember to enable your antivirus again after testing to maintain security.
7. Use VPN
Bypass restrictions by using a VPN. There are various VPN services available; for recommendations, consider the guide on The Best VPN For Streaming and Gaming in 2022. Should these methods prove ineffective, the problem may come from your ISP. In that case, contact your service provider to address the DNS error.
