Pokémon Go: "Failed to log in"
Temporary server issue or poor signal
Login fails right after you pick your account. The help center gives the same causes as for Unable to authenticate: a short server problem or a weak connection.
Fix it
How to fix "Failed to log in"
Check that your phone has a strong Wi-Fi or mobile data signal.
Wait a little and try to log in again.
Force close Pokémon GO and reopen it.
If you log in with Google on Android, remove that Google account from your phone and add it again.
From Pokémon Go's help pages: scopelyexplore.helpshift.com, in our words. Checked on 11 November 2026. If the steps do not help, Pokémon Go's own support is the next stop.
