I get error wow51900314 when trying to log in

Just as the topic says.

When I try to log in into client (i use retail since i want to play on the latest version and I wanna stay up to date with the lore) i get this error:

We couldn’t verify your account with that information (wow51900314)

I did create account before that and bnetserver.exe and worldserver.exe are running.

I think I did something wrong when setting up the server but i don’t know what.

Thanks in advance.

Use https://github.com/Arctium/WoW-Launcher/releases to start wow

I will check it out.

Alright so I can now log in but when realm list pops up the ‘trinity’ realm was incompatible so i changed the ‘gamebuild’ in the realmlist to match the game version i have and I rejoined the game and entered the realm and now its stuck at ‘logging in to game server’ window.

Or is that what I was supposed to do?
