What happened when you tried to sign in again? Have you tried another WiFi?

I also have the same issue and did a factory setting to no avail. Please advise

Same thing with different wifi or after restoration and even reinstall the google app

Do you have access to another WiFi network where you can try? That has worked for several people.

Try a restart.

Restart your iPhone, iPad, or iPod touch

Try a forced restart.
