PoE2: "Failed to connect to instance"

Changing servers helped me as well.

Got this problem since last night, whenever I open a portal to go back to my hideout then it logged me out and the error message pops out. I'm able to login back after I changed servers, but once I open up and enter my portal to hideout then it failed to load instance again. I thought my hideout is bugged so I changed my hideout but still the same problem. Almost 3700 hours on POE 1 and 700 hours on POE 2 not once I got this kind of problem. Any fixes to this yet? It's really annoying I have to change servers every single time.
