Gmail not working on my tablet

[cb2367]

For some reason, Gmail has decided to stop working on my tablet in that for the past two days, it has failed to display new messages. I open Gmail and keep seeing a message that correct credentials are needed. There's a sign in link right next to this message, but it doesn't seem to do anything. I have not changed my Google password, but I have signed into my Google account from other locations. I have been unable to find anywhere in the Gmail app or in the Google app where to logout and log back into my account.

Which tablet? Go to Settings>Accounts>Google​ and see if there's a Sync Error listed anywhere. Also, make sure the sync toggle for Gmail is turned on.
