Wrong region, clock out of sync or DNS
You get an error on the login screen that has nothing to do with your password, or the login times out. Riot points to the wrong region, a server problem, a PC clock that is out of sync, or DNS trouble with your provider.
How to fix it
Check that the client is set to the region where your account lives.
Check the server status for your region before you change anything.
Sync your PC clock with internet time in the date and time settings.
Switch to public DNS servers such as 8.8.8.8 and 8.8.4.4, then flush the DNS cache.
If you use a Killer network adapter, turn off Advanced Stream Detect in the Killer app.
