I received the DNS Probe Finished Bad Config mistake on Chrome browser some days once I fixed yet another similar mistake- DNS Server Not Responding. This error also impacts other browsers such as FireFox, Edge however you get the error in a different format. If this error happens, you’ll have to refresh the web pages a few days before it loads correctly. Then it again stops loading and then you will need to refresh it over and over. Bloggers have posted a lot of fixes for the Bad config mistake, but not all have worked for everybody. I tried quite a few alternatives myself however none of them were quite effective i.e. they worked only temporarily. Then I decided to try something myself. Guess what? I managed to fix this error quickly and almost forever- because I fixed it three days back and I am still not getting the mistake on my PC.
