I tried to install signal-master (https://www.npmjs.com/package/signal-master) on my Droplet. This node module has the task to build a signaling server for WebRTC on port 8888. The server is used by SimpleWebRTC (https://github.com/andyet/SimpleWebRTC) which needs a signaling server to establish a peer-to-peer connection.

I could successfully install and run the module on my one-click node.js Droplet:

signal master is running at: http://localhost:8888

When I open my WebRTC page, the connection can’t be established.
The url the script is looking for is:

https://signaling.comsimulator.com/socket.io/?EIO=3&transport=polling&t=1549976813646-5

But that page doesn’t even exist (404).

Do you have an idea to make it work properly?
Thank you very much in advance
