Is there an existing issue for this?

I have searched the existing issues

Current behavior

When i try to connect to a mqtt broker over wss on a different port than 8081 it will not work.
It says it is connecting via port 443, but in the console you see in reality it wants to connect via port 8081

Steps to reproduce

Setup a mqtt broker (emqx for example)
Put a reverse proxy infront of emqx (traefik for example) and provide the wss connection on a different port (443)
Try connect via hoppscotch

Environment

Production

Actually, it doesn't always use port 8081 because other ports can be used. But why can't we use port 443?
