Can't connect to realm after update

I can’t connect to any realms. I get to the realm selection, once I try logging in, it sits at the “logging into realm” screen for a minute then kicks me to the main screen logged out. When I try to manually log in and try again, I get the error “wow51900319”. Any ideas? I can connect on my crappy laptop though no problem. I did some windows updates during server maintenance and it hasn’t worked since.
