- If your Internet connection works perfect but you still can’t authenticate, disconnect and reconnect to your network.
- If you’re using cellular data, try connecting to WiFi network in your smartphone and log in. If you’re using WiFi in your smartphone, switching to cellular data or connecting to another WiFi to see if it works.
- While you’re on the login screen of Pokémon Go, turn on the Airplane Mode in your device. This will disconnect your network and signals for a while. Then turn off Airplane Mode and your phone will reconnect to network. Then try to log in again to see if it works.
