I do get constantly kicked from the servers (used to be goblin, now Saragantas) with the 90002 error. This goes back to the server relocation back in spring 2017. After months of frustration i canceled my sub and i came back ~3 weeks ago just to find myself in the exact same position. Random disconnect with 90002 without a warning or a lag before it happens. It is so damn annoying, i thought this would have been fixed by now

I know the problem is not on my end. But since you asked for more informations here are mine:

Platform: PC
Connection type: wired
Other programs running while playing: Firefox, Thunderbird, Discord
Any patterns: No, it happens randomly in random areas. It seems to happen more often while in a duty (dungeon)
What i have tried to resolve the issue: Tried different VPN's, tried different computers. Nothing helps.
