LowMS server not showing up in game server list after today's patch.

After every patch, I run the Steam Update in LowMS so that the versions match. No exception this time. I've done all the troubleshooting I could find online as well (checked the server region set in the configuration files, backed up and deleted the game.db file in LowMS, and tried direct connect and connecting via Steam Favorites). I do not have any mods installed, not on my PC and not on my LowMS server. The server was running just fine before today's patch. Does anyone have any advice on how I can fix this?
