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. Had my friend submit the exact same ticket on his account and it went through. Does my account have some shadow ban or something?
It sounds like you may be having a disconnection issue, have you tried the following troubleshooting?
01.12.20 Entered Naxx 10m for Xmog on my DK after killing the first boss entered the next room and was disconnected from the server and since 01.12.20 cant log back into server and to character list keeps disconnecting me with error WOW51900328. Ive folllowed read and done every step to fix the problem but no results till now. if anyone knows how to help pls pst.
Another article that you might read.
This is a problem on their side. They have tonnes of DC-loop places in Shadowlands.
It’s not my internet, its not any addons, its NOTHING on my side.
So many are experiencing this crap, it’s like this is just programmed by some who is only halfshaved.
Happens way too frequently.
Jumping down to last boss in plaguefall:
Stuck in DC loop
Yes I tried all the following on that link. I even logged in at a friends house who has fiber internet and the problem persisted. He’s able to log in just fine and continue playing.
Had same issue scan/repair did fix the issue. Can give that a try while you wait on a reply
happening to me as well but only on one character, all other characters are able to log in
I have the same problem and cant log in with any of my characters T_T
I’m getting the same error. I log in, can play for about 1 minute and then get DC’d with the WOW51900319. It’s been happening since I activated my account a couple of days ago. The weird part is it’s intermittent… sometimes I can play for hours at a time but mostly I get dumped within a minute of login. I’ve run all the Blizzard troubleshooting and everything seems fine.
Its been ten days till now since i cant log into server and into character list keeps disconnecting me with error WOW51900328.have only 4 days left in my subscribe for this month and i really dont know what to do.Ive tried EVERYTHING written down here to fix that error but till now nothing changed. was hopeing on the servers restarts or fixing days but also nothing happened after them.I really hope that the Blizz team will come out with a solution to get the problem fixed. We are all counting on you guys. good luck.
I am facing the same issue with my main Monk Char but everything works fine with my DH alt which is so odd. Anyone else facing this issue?
Everytime I login to my monk char the screen freezes then I get the error WOW51900328 and disconnects me. My network is fine, internet is fine. And I did all the diagnostics on WOW’s support blog post. Uninstalled addons, replaced cache files, etc. Still does not work for my main 
Blizzard support please fix this, I want to play my main!!
