Hi,
I haven’t been able to play for several days now.
Always get this message:
Yoy have been disconnected from the server.
( WOW51900319)
Anyone knows what to do?
Try this first https://eu.battle.net/support/en/article/7549
And then use the unstuck character service.
Thanks, seems to work, but as soon i try to enable any addon i get disconnected after a few seconds!
Generally this means one of your addons is conflicting with WoW. Which is good news, because this means you discovered your disconnect issues.
Try to update them through Curseforge or you may have to keep them entirely disabled and/or seek a replacement.
Will try that!
Dosen’t work, no addons installed, can login but not do anything, disconnected after 30 sec. 
I have the same issue. When I login I get error (memory) when I login with all addons disabled I can login.
However when I login in the open world it doesnt occur most of the time, but when im in dungeongroup the error appears.
Pretty sure its some addon, gonna analyse it futher today.
