wss is the WebRTC Signalling Server. You would need something a little more complex than just a standard hosting package. If you are feeling like really digging into this you can find a well-documented example of setting up a video and text chat application using WebRTC here:
If you just want to set up the server, jump to step 5, "Set up a signaling server and exchange messages"
I haven't tried it myself, so i don't know if this server would be compatible with Construct2 right out of the box, but it's worth a shot!
