when are on the public internet, two person can't see each other's video

[dongdongpo66]

Within a local area network (LAN), two people can video chat and see each other. However, when they are on the public internet, they can't see each other's video feed; they can only see each other's names. The application is deployed on the public internet, and I have also set up a TURN server. Additionally, I've tried using https://muazkhan.com:9001/demos/dashboard/, but still can't see each other's video. What could be the issue? Is it the signaling? Or the TURN server?

Is this translation helpful for your needs?
blown is my turnserver test:
