Extra: This started happening last night for me. So far the only instance I've attempted to access is Castrum Meridianum. So I guess it's possible it's just with this instance. But if I find a group in Ultros that's full and go with them I can get in with no issue.

Update: This is happening with full parties now that I find in my own server.

Just started experiencing this myself today. First time was probably about 3:00 PM (central standard time). I'm able to use the Duty Finder to que for The Bowl of Embers (Hard) but keep getting 90k error every time I try to enter Castrum Meridianum.

Getting this now as well. Unable to get back in.

After a couple of minutes you'll be able to get back into the game. You'll get a 90k error for a couple of tries but you'll get back in.

Have waited in queue for an hour twice today to do Castrum Meridianum, with this same behavior. Can't progress in the story because I keep getting kicked out.

More than a little frustrating.

It's also ruining my Instances experience. And no you usually cannot get back in because by the time you pass through error 10102 you will have been kicked from your party AND will be left with a 15 mins lock-out.

I meant back into the game, not back into the same instance. I haven't had any 10102 errors after this. I get booted from 90k. When I try to log back in to the game I get a few more 90k errors before I finally get into the queue. When I actually get back into the game I'm no longer in the party, but don't have a 15 minute wait in the DF.

Probably takes up 5 minutes of my time from the first 90k to finally getting to log back into the game.
