How can I install signal-master properly on an Ubuntu node.js one-clock Droplet?

I tried to install 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 ( 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:

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

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

I just signed up to ask did you ever get this working? I’m stuck at the very point you were almost 2 years ago. Still no good information out there. I also get 404.
