Why does a DNS error occur? DNS errors occur essentially because you're unable to connect to an IP address, signaling that you may have lost network or internet access. DNS stands for Domain Name System. In other words, the DNS translates your web domain name into an IP address and vice versa.
The problem might be related to your DNS cache, so flush it out. To flush the cache, type ipconfig /flushdns at a command prompt. Your ISP could be the source of the problem. One possibility is that one of its DNS servers is down and you're trying to access the downed server.
'DNS server not responding' means that your browser was unable to establish a connection to the internet. Typically, DNS errors are caused by problems on the user end, whether that's with a network or internet connection, misconfigured DNS settings, or an outdated browser.
