Hello nosno, are you still having this issue? I found on google's site they received many reports about authentication but now resolved.this link may be helpful to identify if any sync issues are occuring with google.
This link may be helpful to troubleshoot and identify if there are any issues reported with google services:
Yesterday I started receiving "gmail authentication error" on my phone. I tried the link that was suggested and the gmail page reports no errors. I checked my account online and able to login there. Anyone else start getting this error recently?
remove then add the gmail account.
I'm having the same problem. I removed the mail account, and now it will not let me readd it. It says I already have a Google email account. I tried to remove the whole Google account, and it says that the app is integrated into the phone and that I will need to initialize (factory reset) the phone to remove the Google account. What now??
I've been unable to remove google account..I click on "remove account" and then nothing.
I have no isues using gmail using gmail application, just that I keep getting this annoying "Gmail authentation error" popping up on my phone every 5-10 minutes
is unable to remove the account
Does this mean I gotta do a factory reset??..ugh..I just downloaded apps to this...(groans)
Authentication errors are usually resolved by removing your Gmail account. You must do a factory reset in order to remove the original Gmail account on your phone. Please do the factory reset and keep us posted.
