Well, I also encountered this problem. Right in the middle of the game, the map stopped loading, then the connection was lost, and none of the characters could enter the game.
I don't think this is related to blocks within Russia, as I have a German IP address (private VPN server on vless) and everything else works fine on it.
The solution was to connect using VPN Amnezia (to connect to which I first have to connect to my gateway), but the free version only has a speed of 8 Mbps.
At the same time, when I try to connect from my VPN, I cannot
1. Get client updates
2. If I do manage to launch the client, I can log in until I select a character (my credentials are saved in the client)
3. After selecting a character, I cannot log in.
I am willing to provide any diagnostics on my end, if necessary, to solve the problem, as it seems that I am not the only one experiencing it.
In any case, I realize that the problem is on my end, so if it is not resolved, I will simply change my hosting provider.
