Today 17 november Google dropped support for an old Google calendar API. I was using provider version 0.25 with lighting 2.6.6 with thunderbird 24.4.4 and all of my calendar did not work: a popup asking for a password was continuously appearing.
I deleted all calendars, removed old version, restarted thunderbird as requested, installed the current version, added again my google calendar. I was required a password and the verification code (as my account is protected by the two steps verification). Now everything works again.

I therefore suggest to people complaining about non working calendar to try following the same procedur I did.
