Hi everyone, We need to open a separate port (e.g 81) on the cloud beside port 80 which is normally open to serve the app, we need to use this port to enable WS connection on an small WebSocket server inside our app. I also think that maybe possible to designate a sub-path inside Mendix runtime WebSocket to serve our scenario, what I mean is to use the WebSocket that Mendix runtime already uses it to talk to UI, like ws://localhost:8088/reload/ , if you stop Mendix runtime somehow then you’ll see that UI is complaining about loosing connection. browser developer console can help you to see this in action WebSocket connection to 'ws://localhost:8088/reload/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED Does anyone know about this ?
