Unable to visualize camera when not on the local network

[rjam92]

Hello,

I followed the instructions for launching and connecting to the robot web interface as described in the readme file of the stretch_web_interface git repository. I am able to access the server of the robot but the camera feed does not show up and I cannot see any choice of robots to select from on the operator side even though on the robot's end everything is fine and the camera feed shows up as well.
The robot and the operator are on different networks.

I am confused why no robot shows up in the drop down menu on the operator website and why the camera feed is missing even though I can access the website?

Any hints will be useful. Thank you.

This question is being answered on the forum here. For the use case of different networks described here, a signaling server must be created in order for video data to be transmitted between the robot/operator over WebRTC. More details on creating a signaling server can be found here.
