Consistent, immediate disconnect upon changing 1+ zones.

I made a post about this yesterday in what I assume is the wrong forum: https://www.pathofexile.com/forum/view-thread/3456943

I played some of Crucible League and all of Trial of the Ancestors league without any issue. Performance and latency is noticeably much, much worse in this patch. I don't believe these are connected to my issue, but I have heard others are experiencing this so I wanted to say I'm not exempt from that.

To summarize the issue: After changing zones 1(+) times, I will have 'an unexpected disconnection' to the login screen and after that I cannot reconnect to that league on any character for ~15 minutes (presumably until the game tries picking new zones?). The issue occurs on both Standard and Affliction, but it happens for them separately.

The first time I do this on a character in a league, the process works normally.

Usually, the first time I try changing zones, I'll get disconnected during the loading screen with the '>An unexpected disconnection occurred' error. Sometimes I can change zones 2 or 3 times before this happens, but it consistently happens on the first and I am never able to make it past 3 zones as far as I can remember.

Once this first disconnection occurs, I am unable to log into any characters on that league for ~15 minutes. Originally I thought this issue was exclusive to Affliction because I could still log into my Standard characters, but after trying to play (or really just change zones) on my Standard characters, I found that the issue also happens on that league.

When I'm having the reoccurring disconnections, they happen almost immediately at the loading screen for the new zone appears.

After what testing I can do on my end, my issues appear to be with the Japan server(s). I spent roughly 4 hours playing on the Singapore server today without having the previously mentioned issue. I could have sworn I tried different servers (Texas being the third closest server, somehow?) last night and had the same issue on all of them. But for the time being it seems isolated to JP.

It's less than ideal because there's a difference of >50ms ping between JP and SG for me, but at least I'm able to play. I am having the same issue I've heard others voice about the SG server where roughly 75%+ of instances are laggy to the point of being unplayable. In one instance, Ihad a lag spike that lasted at least 30 seconds before anything moved on my screen.

It's less than ideal when playing in the campaign, but at least you can reroll instances until you get a playable one. It makes playing maps really punishing, though. Every map I've spent currency on (I just made it to maps) has been one of the maps where I can barely play the game. Feels bad.
