Failed to connect to instance.

Cannot log in into game.

I'm typing password, choosing character, logging screen to "Oriath" running. After few seconds I'm getting information :

"Disconnect, Failed to connect to instance"

Hello Support,
I have big problem doing maps.... every map, i got
"Disconnect, Failed to connect to instance"
I lost few maps doing and trying and looking whats happend.... Help me plz, i cant play with that, and losing so many maps....

It's all the same for me. Only one or two maps I've done today had no issues with joining instances - the rest whether it is a new map opening form my HO or Zana in already existing map it's crashing the client and disconecting me with the info about not beeing able to join the instances. It's EU servers btw.

I'm suffering the same issue as well since yesterday.
It happens when i try to go into the map "Residence".
I've wasted 2 residence maps so far.
I think it's better not to try that map for a while.

Dev, please fix this bug and let me know.

Same problem. Im wasting maps constantly because the game decide delete the map instance besides of kickes me...

What's with all the map disconnects? I thought at first it was on my end but everything else works fine. I can't do my Ascendancy because I can't go that many maps without a disconnect.

I'm on the U.S. servers.

same here constant crashes and disconnects. Lost an entire temple of atzoatl run today... (São paulo server)

Australian server here, experiencing the same issue.
0 issues before the 3.7.3, on a fresh install (before 3.7.3).

Getting it about 25-30% of when I change zones/etc.

Sane here, even when I log back in and try to go from town to my hideout I sometimes get dc because of this error. I won't even attempt Lab again because I've lost so many offerings from getting dc between zones :\

edit: AUS server btw

FIX THIS!!!!!!!!!
