I have the same problem as you. The cause of my problem is that the hosts file has been modified. You can see if the hosts file of your computer has been modified. Restore can solve the problem.

The following is the contents of the hosts file of a mac computer:

127.0.0.1 localhost 
255.255.255.255 broadcasthost
::1 localhost
