My Streamdeck Mosart Plugin cannot find the server - even if installed on the same host as the Mosart server (AWS EC2 instance). I can easily find
from a browser, even from a local PC. I also see an established TCP connection on the server when I try with the Streamdeck, but the buttons don't work and show an exclamation mark. I am using the Elgato App, not Bitfocus Companion and I make sure that the server is listening and doesn't already have an active connection on that port.
