Troubleshooting
Make sure there are no error messages on the login or registration page.
Make sure you use the correct email and password if you are trying to log in to an existing account.
If the reason you are unable to log in is that you have forgotten your password, you can use the "Forgot password" link on the login page.
Make sure you are properly connected to the internet (Try turning WiFi off/on).
Make sure you are not behind a restrictive firewall (Often turning off WiFi and using the cellular network instead can work).
