Random Disconnects and cannot reconnect because of "realmserver not active"

Hello,
I am playing MOP Classic and since around 3 days I am constantly disconnecting for so apparent reason. I am often unable to reconnect and the client says “realmserver not active” (it is). I already tried the following things and nothing changed:

  • Removed all Addons and WTF ordner, running reparitool from client afterwards
  • multiple router resets, pc restarts
  • firewall exeptions for all WOW versions and Battle net launcher
  • Reset Firewall Settings
  • Deactivating any background apps
  • emptying DNS cache and reset network like explained here support.blizzard /en/article/82450
  • Support ticket created, no solutions but the ones above

Its getting really frustrating because I am only playing since 1 week and everything was running smoothly until like 2/3 days ago. Now especially in the evening I randomly disconnect (classic Error Code: WOW51900319). When I try to reconnect it often stops in loading screen and I disconnect again and it says “Realmserver not active”, but I can see on server status that there are no problems. What can I do?
