If you enter your six-digit 2FA code correctly within the 30-second time limit and still encounter a “2FA Google Auth is invalid” error, it could be that your 2FA application is not properly synchronized with your device's time zone settings or the network time.
*** To fix this, enable network syncing under Date & Time settings on your device.
For Android
Go to System > General Management > Date & Time
Switch on "Automatic date and time"
For IOS
Go to Settings > General > Date & Time and switch on "Set Automatically"
*** If the error persists, we recommend you to delete your 2FA entry and create a new entry using the QR code or the manual key.
*** If still didn't work you may have to disable your 2FA for the mean time. Please check this link for your reference.
