The "DNS_PROBE_FINISHED_BAD_CONFIG" error typically occurs in Google Chrome when there's an issue with the DNS (Domain Name System) configuration on your computer or network. This error indicates that the DNS lookup failed to resolve the domain name you're trying to access. Here are several steps you can take to fix this error:

  1. Clear DNS cache:

    • Open the Command Prompt as an administrator (right-click on the Start menu, then select "Command Prompt (Admin)").

    • Type the following command and press Enter: ipconfig /flushdns

    • Wait for the process to complete, then restart your computer.

  2. Renew IP address:

    • Open Command Prompt as an administrator.

    • Type the following command and press Enter: ipconfig /release

    • Once the release is complete, type: ipconfig /renew

    • Restart your computer and check if the error persists.

  3. Change DNS servers:

    • Open the Control Panel on your computer.

    • Go to "Network and Internet" and click on "Network and Sharing Center."

    • Click on your network connection (Ethernet or Wi-Fi).

    • In the new window, click on "Properties" and select "Internet Protocol Version 4 (TCP/IPv4)."

    • Click on "Properties" and select "Use the following DNS server addresses."

    • Enter the following DNS server addresses:

      • Preferred DNS server: 8.8.8.8

      • Alternate DNS server: 8.8.4.4

    • Click "OK" to save the changes.

  4. Disable VPN or Proxy:

    • If you're using a VPN or proxy service, temporarily disable it and check if the error persists. Sometimes these services can interfere with DNS resolution.

  5. Disable Firewall and Antivirus:

    • Temporarily disable any firewall or antivirus software you have installed and check if the error is resolved. These security programs can sometimes block certain DNS requests.

  6. Power cycle your router:

    • Turn off your router and unplug it from the power source.

    • Wait for about 1-2 minutes and then plug it back in.

    • Once the router is back online, restart your computer and check if the error is resolved.

If none of these steps resolve the issue, it's possible that there may be a more complex network configuration problem. In such cases, it might be helpful to contact your Internet Service Provider (ISP) for further assistance.
