You may have faced DNS_PROBE_FINISHED_BAD_CONFIG error on your chrome or any other browser while accessing internet. This Error occurs when there is some issue with your modem or DNS server settings. As the error code name says this is a DNS related error. DNS is used to translate names of websites in their respective IP addresses. This error can be easily fixed by changing your DNS server, While there are also some other basic troubleshooting methods which may help you out in fixing this error.



I have written three troubleshooting methods using which you can easily fix DNS_PROBE_FINISHED_BAD_CONFIG Error. First two are just normal troubleshooting steps which is usually used to troubleshoot common network errors.

#1 – Renew Your IP

This method is used to renew your IP address, If there would be a problem in your IP address then this method will fix the issue.

  • Type cmd and hit enter.
  • In command prompt type the following command :

ipconfig /release

This command is used to release your IP address.

  • After your IP has been released type ipconfig /renew to renew your IP address.
  • Exit command prompt and the error would be hopefully solved.

#2 – Flushing DNS Cache

If there is a change in the DNS Server and your system is looking up for its local cache to navigate you to a website, Then this may cause DNS_PROBE_FINISHED_BAD_CONFIG error. So by flushing your DNS cache you can fix this error.

  • Go to start and search for cmd.
  • Open cmd, and type the following command.

ipconfig /flushdns

  • This command will flush the dns cache and the error will be fixed.

#3 – Changing the DNS Server

As said earlier this is a DNS related error, So it can be easily fixed by changing your DNS server. It’s recommend to use a public DNS server as they are fast and reliable. So to change your DNS server follow the below guide :
  • Press Windows + R to open the run window.
  • In the run dialog box type ncpa.cpl and click ok.
  • This will open your Network Connections.
  • Right click your active internet connection and select Properties.

  • The properties window will pop up, In the properties window double click Internet Protocol Version 4 (TCP/IPv4).
  • Now select Use the following DNS server addresses and enter the following Preferred DNS Server and Alternate DNS Server addresses :

The DNS address listed above is of google DNS. You can use whatever DNS server you want, But I personally recommend Google DNS server as it’s very fast. You can also checkout list of best DNS servers.
