this problem happened with me, i have MacBook Pro. so to solve this problem for who use google chrome or safari, just change the ip Address to 127.0.0.1 local host.
MacBook Pro 13", macOS 10.14
the Steps are:
1- go to network( wi-fi ) on the top.
2- click on it.
3- select Open Network Preferences.
4- wi fi window should be open then select Proxies.
5- in the box under ( bypass proxy setting for these hosts &Domains ) write ( 127.0.0.1 )
6- click ok.
all set now use it normally.
