I had this problem, after trolling through the internet for about six hours, I found a solution.
Open your cmd.exe (by typing cmd into the run box) then type ‘netsh winsock reset catalog’ without the quotes, fixed the issue straight away.
You will likely need to reauthenticate your login, though.
I would like to ask to STICK UP this post.
Man, I will never thank you enough for your post!!
It finally solved my problem!!
