That is very odd. Have you tried something like CCCleaner on it? Does it happen with all browsers (IE11, Edge, FF, Opera, Chrome)?
Yes it happens on all browsers I tried (Chrome, Firefox, Opera, Maxthon, Edge). I tried CCleaner and PC Registry Mechanic... no changes...
After few seconds, it throws "Error code 118 (net::ERR_CONNECTION_TIMED_OUT)".
Resetting PC will probably fix this but I don't want to reset my PC just for this...
It's almost like some software on your PC might be blocking the site. Do you have a security suite that has URL blocking rules that you can check? Other than trying the hosts file fix, I'm at a loss. Does ping and tracert work? That might give you some insight on where the block is occurring. I would also completely disable the Windows built-in Firewall.
I can ping "google.com" and "8.8.8.8". But I can't ping "www.google.com".
I'm not a network expert. So I don't have a clue how to fix it. I'm searching through internet. Thanks anyway.
