Please clear your cache, flush dns then relog, if you are still facing this issue when you log back in, please let me know.

The following link will show you a tutorial on as to how to flush your DNS:

If none of those worked for you, then I would suggest either trying to login via browser, or a different browser, or attempting to use a VPN to login.
