Unfortunately, the server code isn't quite capable of handling 2.4.3 clients yet. Apparently, Blizzard has changed packet structures for the realm list (or logon-server), so a bit of time is needed until the newest patch is supported.
If you've already patched to 2.4.3, follow the process located in this thread to revert back to 2.4.2.
