Client gets stuck when changing locations

Playing on M1 MacBook Air.
I've encountered an issue when moving to another location, no matter what this location is, the client gets stuck on the loadscreen with nothing else happing. Tried to restart the client then, but it doesn't help - lab progress gets lost, obviously, but map portals, surprisingly, don't get wasted.
I wonder, if there are any solutions to this?

common issue on pc from time to time.

there has never been a technical explanation from ggg what caused it, just that they fixed it (again).

from what i got, switching instances makes your client connecting to another port on the same or another server and there is a verification system that your client is allowed to connect to that port.

so either the instance server gives you the wrong port or the wrong access key.

tl;dr it's ggg's issue
