Check your connection first, then the service region, login status and browser settings to locate the cause.

Steps

Confirm the app is connected and open an ordinary website. If that fails too, complete connection troubleshooting first.
Connection troubleshooting
Choose a location in a region supported by the service, wait for connection and reopen the service.
Read the error message. Log in again if your session expired, or wait as instructed if you hit a rate limit.
Check again in a private browser window and review extensions and proxy settings one at a time.
Browser troubleshooting
Record the service, error, time, selected server and app version, then open a support ticket.
