Calendar not synching

[vEEP pEEP]

Hello,

I open up my calendar on my desktop (W10) and it tells me there is an error that needs to be fixed. It then opens a Windows that is Gmail (I sync these calendars). It takes me to the login screen, then password, I put in my password and get this error:


I do have two step authentication, but it craps out before I can enter the code.
Even after a reboot. Suggestions?

Thanks,

Mr. V
