Only Working One Direction

[darkmagedtm]

I've used this off and on for years (I wipe my computer decently often, so regularly have to set it back up). I'm using it to talk to my local directly with ws://homeassistant.local:8123/api/websocket, and for some reason, it only works one direction. I can populate the list of scenes and buttons. If I change the state of a button via a dashboard, the stream deck button reflects the new state immediately. But pressing the buttons does nothing, and I can find nowhere in the logs where it's hitting the websocket. Any ideas what I'm missing?
