I am using the EMQX template Deploy EMQX | Railway to spin up a MQTT broker. After following some guides here Can't connect to EMQX - Railway Help Station I was finally able to connect to the unsecure public port; 11502:1883 (via mqtt and not mqtts).

I want to connect to the service via secured ports and also via websocket, please how can I do that? I've tried all the combinations I can think of, and nothing works, please help.
