Not working outside LAN connections

[juliangorge]

Hello @kmturley !
I really appreciate your time in this project. I have been trying to build a docker image to use it in AWS EC2 instance (also to make compatible with those libraries versions, etc). With no-changes applied in code, I deployed it and successfully connected with devices inside the same LAN net, but when I try to listen a "remote" broadcast, I don't receive any error or message or signal.

I could find what exactly is wrong, and I will be so grateful if you can give me one hand.

Regards!

Hello,
Thanks for trying out my prototype. As mentioned in the README, I only tested it on local networks. It was out-of-scope of the project to also have a hosted version.

However in theory you should be able to get it to work. Key things to check/configure:

• Check both https:// and ws:// protocols are supported
• Check the port 8080 allows traffic
• Check console logs on both client and server to see which events are being fired

Hello Kim, you do not know how I appreciate your time in your response.

Actually, I checked these 1-2 bullet points, but I can not understand how to debug client and server functionality. Although I will continue trying to.
I think it need ICE (Stun and TURN) settings to work fine across any device/NAT/Firewall configuration. Do you consider add it for a new release? :)

Again, thank you for your time.
Regards

I'm not familiar with ICE (Stun and TURN), would need to investigate more.

But a quick search found this code:

const configuration = {iceServers: [{urls: 'stun:stun.example.org'}]};
const pc = new RTCPeerConnection(configuration);

Compared to my code where I don't pass a configuration:

this.conn = new RTCPeerConnection();

I will mark this as a feature request. Although I don't have time to look at it now. Can revisit at a later date, or accept a PR if someone can implement.
