unable to validate game version

[Th3AnG3L]

Hello i follow the steps how to create the server
but when i open client wow.exe and try connect it shows this error "wow unable to validate game version"
on bottom screen it shows version 12341
on db i see it shows 12340

how i can solve the issue?

Get a correct client. 12340 build is for 3.3.5a. 12431 is something custom

I have been running this server for quite some time and the server restarted from updates, then I added another realm and now I am getting Unable to Validate Game Version.
Game Version says in the bottom corner: 12340
Database says same number in the realmlist table under gamebuild.
in the auth table, it is now showing another row: 13930 3.3.5a
Is there someplace else that I could be missing something, that I should look at?
Do I just update my client to the new build now? Delete that row in the DB?
