And the obvious possibility I had intended to but forgot to suggest -
- were you checking your external (public facing) ip address
dynamically assigned to you by the isp? As in, perhaps it was DHCP
with a 36 hour timeout, and instead of existing address being renewed
a new address instead was being assigned (a bit dodgy but possible),
and that for some reason your login on google on the google side had a
problem with this.
You see Google makes some assumptions, and may be prefers people use
web gmail over pop/imap. You said other google things were not
working, so perhaps we are homing in on the culprit of your problem.
Good luck
