This issue appeared to resolve itself last night at approximately 9:40 PM Pacific Time. I was able to log in, complete a trial, and do some non-instanced tasks as well without any issue. However, when I tried to log in this morning again to complete my daily quests, I was unable to connect again. I'm receiving the same error.

FC mates report that they can see a message about me logging in, but that I still am listed in the "offline" portion of their friends list. When I get kicked, they never see a notification about me logging out.

On my second try I was able to log in and things seemed OK, however after a few seconds I noticed my TP was no longer regenerating and about thirty seconds later I was kicked with the same error once again.
