When you trying to open website, at that time you found that your browser (Especially in Chrome) shows some problems about DNS that is called “This webpage is not available” and the Error codes is “Error Code: DNS_PROBE_FINISHED_BAD_CONFIG ”. In most cases, the IP addresses used by your ISP’s domain name servers are automatically set by your ISP via the Dynamic Host Configuration Protocol (DHCP). The server at which you trying to connect can’t be found, because the DNS lookup failed. DNS is the network service that translates a website’s name to its internet addres. This error ” DNS_PROBE_FINISHED_BAD_CONFIG ” is most often caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.
In this case you need to use Google Public DNS. To use Google Public DNS, you need to explicitly change the DNS settings in your operating system or device to use the Google Public DNS IP addresses. The procedure for changing your DNS settings varies according to operating system and version (Windows, Mac or Linux) or the device (computer, phone, or router).
