The lobby server connection has encountered an error 2002

[Nari92]

Hello.

Earlier today I kept getting this 90002 error when playing the game. About 3-4 times if I remember correctly. Then, after a while, I got the "lobby server connection has encountered an error 2002" message when I was in loading screen for a dungeon, and now I can't seem to even get into the character selection lobby.

I've tried to read up on it, to see if I could find a solution, but couldn't really find anything. Some people says it's their router or firewall etc.
Now, my problem would be that I do not own the router I'm using, so I can't do anything about it.

I usually have no problems logging in and playing, so now I'm kinda worried..

Does anyone know how to fix this error? :<


EDIT 1: I could get into the lobby just now, but got the 90002 error again D:
