WebSocket connection to ‘wss://mydomain.com:8443/’ roslib.min.js:1 failed

What is the issue you’re encountering

socket is not opened

What are the steps to reproduce the issue?

I have ROSbridge websocket server run on wss://mydomain.com:8443
I also have Apache2 hosting a webpage on https://mydomain.com
This setup run normally on the host but not the client side.

How can I use WSS to send and receive data between server and client
on my domain through port 8443

I’ve found this 'redirect-websocket-port-443’post but not clearly understand what exactly should I follow

This is what I’ve config
0. toggle On WebSockets

  1. Add DNS table Type = CNAME,Name = wss,Content = mydomain.com

Custom filter: URI Full, wildcard, wss://mydomain.com/*
2. Origin rule: Destination Port Rewrite to 8443
3. Cache Rules: Bypass cache
