Since this is DNS issue, you can fix using below steps.
Go to start > type “services.msc” without quotes
Now search for DNS client
Once you do this, close your chrome browser and reopen your web page. That should fix your error.
If you are using windows 8, proceed with same theory with “services.msc” but to get there, either swipe in from the right, Windows key + C, or put mouse cursor to the top right or bottom of the screen. Click search and type in “services.msc” no quotes.
