This is happening way too often. Any dev/admin help besides "We're looking into it?"

Been happening more and more often. Several peeps with issues login in are using AT&t net. When flipping over to hotspot on their phone lets them login in and play as long as it isnt AT&T also.

I'm having the same issue using Comcrap in FL.

Happening once again. Might there be an increase in occurrence of this problem because of the recent patch?

Yes, it's happening to me too.

I logged off for 20 mins to tend to my dog and now ... this sucks. In the middle of a snow/ice storm too.

Same (without the dog).
