DNS error generally occurs due to the incorrect DNS settings, changed IP Address and Firewall issues. Sometimes because of outdated data or incorrect information containing HOSTS file may also generate this error. Still, if you don’t remember adding listings to a HOSTS file, it silently may contain listings, for the reason that some Internet accelerator tools edit them automatically without giving you any notification. Open your HOSTS file by using Notepad and see if the website you cannot connect to is listed there or not. If it is in the list then delete the entry, and after it, you should be able to connect.
