Fix DNS Probe Finished Bad Config Error
As you surf the internet, you are likely to have faced the DNS probe finished bad config error when opening some web pages. The cause for this issue is mainly a network connection error related to DNS configuration.
DNS stands for Domain Name System. DNS is a vital part of the internet that maps website names with their IP addresses.
For example, our website several.com has an IP address of 45:154:166:31; it would be impossible to memorize that number every time you visit our website.
DNS maps that IP with our domain name, so whenever you search for several.com in the URL bar, the computer recognizes its associated IP address and sends you there.
Sadly, this error is not limited to one platform; you may come across it on your android devices or your PC web browsers, like Chrome or Firefox.
Without getting into all the technicalities, the DNS probe finished bad config is an error related to DNS connectivity and configuration.
This error's cause can vary between the following:
- Third-party software
- Faulty DNS configuration
- Internet Speed
- Browser settings
