Is http://localhost:5333/api/info the correct URL, where your LedFX-Server is running?
Is it on the same machine as HomeAssistant?
Is your ledfx config yaml maybe defining host to "127.0.0.1" ?
If so, change it to your IP or maybe 0.0.0.0 will also work

ok my fault...
My ledfx version was too old😅
I installed dev version 8.4 and now it works
