Understanding DNS and its Role

Let's first grasp the idea of DNS before delving into the intricacies of the "DNS_PROBE_FINISHED_BAD_CONFIG" problem. The domain name system, or DNS, serves as the phone book for the internet. It changes computer-readable IP addresses like from human-readable domain names like www.example.com. We may now simply visit websites by entering their domain names rather than their difficult IP addresses, thanks to this translation.


Your computer or device encounters the "DNS_PROBE_FINISHED_BAD_CONFIG" issue when it is unable to properly connect to the DNS server. The website becomes unavailable as a consequence of your browser's inability to identify the IP address connected to the requested domain name. You will often get a warning similar to "This site cannot be reached" or "DNS_PROBE_FINISHED_BAD_CONFIG" when this problem occurs.


This inaccuracy may arise as a result of a number of circumstances. Let's examine a few typical causes:

  • DNS Server Misconfiguration: This issue might be brought on by incorrect DNS configuration. Make sure your DNS settings are correct and adhere to the suggested values.
  • Interference from a firewall or antivirus program: On occasion, too strict firewall or antivirus settings may prevent your browser from connecting to the DNS server, which may result in the "DNS_PROBE_FINISHED_BAD_CONFIG" error. You may identify the problem by modifying your security settings or temporarily deactivating them.
  • Router Configuration Issues: Problems with your router's settings might prevent a connection from being made to the DNS server. As a first step in troubleshooting, make sure your router's settings are established properly and think about restarting it.
