We couldn't log you in with what you just entered. Please Try Again (BLZ51900003)

There is a thread where I posted in at least two times over on the Tech support forum

BLZ51900003 & WOW51900325 every time I try to log into my two accounts. Where's the hotfix?

No two accounts on the same bnet can connect at the same time. If you switch servers, one of them will disconnect every. single. time. Hello? Is this going to be another month long thing that we have to live through?

the workaround mentioned there doesn’t work for me.

with two WoW clients open, attempting to change realms will get the error. have to reenter password
