You have been disconnected from the server. (WOW51900319

Just bought the game 1-month subscription. I was playing on the server Bleeding Hollow with a friend. We got into a PvP battle and kept getting killed while returning to body to spawn. All of a sudden it logged me out of WoW with the error code provided as the title. That occured yesterday 12/2/2020. Spent the rest of the afternoon trying to find/test solutions (none of them worked). Tried to sign back onto the same server/realm today and moments after loading in; I was logged out with the same error message. Not sure what to do besides contact support except submitting a ticket won’t go through and the file size is under 15mb. Does anyone have any idea on what I could do?
