Repeated "Failed to Connect to Instance" - Bug Ref# 1017799522

At Beijing time 2025.5.14 18:15, I encountered the same "Failed to connect to instance" issue again (Bug Ref# 1017799522).

This time it happened twice in a row:

A T15 map with boss and Expedition mods.

An 80-level Expedition map.

These maps are very important to me and the losses are significant.

I have reported this issue multiple times (previous Bug Ref# include 1,350,923,833 and 2,946,449,955), but I have yet to see any response or improvement. This problem keeps happening, and it's becoming extremely frustrating.

I sincerely hope the development team can seriously look into this issue and improve the instance connection stability as soon as possible.

Thank you.
