verifying google account?

my kid accidently reset his alcatel pixi 4 and when its asking to sign in with a google account the phone has been previously synced with I enter my details and it keeps going back and telling me to verify the account again, however when I log into my email address on the computer its saying ive signed into the phone, been trying to fix it for hours.

Is the Google account that you say you synced with also the one that you used to initially set up the phone? It needs to be.
