How to fix the “ERR_NAME_NOT_RESOLVED” error? If you receive this ERR NAME NOT RESOLVED error on your PC, you can try the following methods one by one until the error gets fixed.

# 1. Check Your Internet Connection

Poor Internet connection can cause the “this webpage is not available ERR_NAME_NOT_RESOLVED” error easily. So, when you encounter this error on your device, the first thing you need to do is check the Internet connection. Here are some ways you can do this:

  • Try accessing the same website from a different Wi-Fi.
  • Restart your router and reconnect it again.

# 2. Disable Antivirus and Firewall

Sometimes, the installed antivirus program and firewall may block you from accessing certain websites and then result in the Chrome ERR_NAME_NOT_RESOLVED error. In this case, you can try temporarily disabling the installed antivirus program and firewall to fix this issue.

# 3. Clear the DNS Cache on Your PC

The “ERR_NAME_NOT_RESOLVED” may also be caused by the outdated cache items on your device. So, you can try flashing the DNS cache to fix this issue. To do that, you can do the following steps:

For Windows:

Step 1. Press the Win + R keys to open the Run dialog, type “cmd” in the box, and press Ctrl + Shift + Enter keys simultaneously to open the Command Prompt as administrator.

Step 2. Enter the following commands one by one, and press Enter after each command:

  • config /flushdns
  • ipconfig /renew
  • ipconfig /registerdns

Step 3. After that, you’ll receive the message “successfully flushed the DNS resolver cache”.

For macOS: Open the Terminal window, type “dscacheutil -flushcache” and press Enter.

For Linux: Enter the command “sudo /etc/init.d/nscd restart” in the init.d subdirectory. If you want to flush the DNS cache with Systemd, you can execute the command “systemd-resolve –flush-caches” and “systemd-resolve –statistics” sequentially.

# 4. Check the Browser Settings

If you still find this webpage is not available ERR_NAME_NOT_RESOLVED after clearing the DNS cache, you can suspect there is something wrong with your browser. As Google Chrome has its own DNS cache, you need to clear it as well. Here’s the way:

If the DNS server does not work correctly, it can also result in the Chrome ERR_NAME_NOT_RESOLVED error. In this case, you can try using a Google Public DNS server address to fix the error. Here’s how to do it:

Google Public DNS Addresses:

  • For IPv4: 8.8.8.8 and 8.8.4.4.
