what issues are you running into?

ccfdc134-86d5-4fc6-a8d7-f138883659e2

I couldn't use the ws connection, I didn't understand which url to use or the port

Connection using mqtt protocol works normally

wss://:

caddy public domain? just?

what does caddy have to do with this?

there are two domains > caddy-production-bf9e.up.railway.app,
The other domain is junction.proxy.rlwy.net, I used this to access the mqtt protocol

you would use the TCP proxy

Sorry, I couldn't understand, I tried several ways, but it didn't work

Where could I be going wrong?

^ what happens when you use this format

I'm trying to connect using mqttx, it requires a port even in the wss protocol, when I try to use the ports that are in the env, it doesn't connect, it keeps reconnecting

then you would need to provide the port

^ updated

This works, but only on the mqtt protocol

domain and public port

may I ask what you need websockets for?

Use on mobile

you said the mqtt protocol works fine

yes

It didn't work, for mobile use the ideal is ws or wss, I don't know why, but I couldn't use the EMQX template
