Unable to connect to WebRTC on the browser after running the code.

[JimBeam2019]

Hi Will, thank you for sharing the WebRTC Game example code. I was intrigued by what WebRTC can do on gaming after watching your YouTube video, so I've tried out the code. But I've failed to generate the same result as yours in the video, and I hope you could give me a hint on what I may have gone wrong along with the steps.

So, after cloning the project to my PC(Debian Linux), I added the localhost IP (127.0.0.1) to the main.go file as the instruction says and ran the command line go run . in the terminal (go version: go 1.17.6). The result showed as below.

Listening for WebRTC traffic at [::]:80

Then, when I opened a browser (Chrome) with http://localhost, what I was given was a web page with a message input area and a Send button like the pic. There was no game action area and the terminal didn't have any further updates from the terminal either. I'm not sure what had gone wrong, so could you give me any advice, please? Thanks.

Hi! You also need to add the address of your server to:

webrtcGameTemplate/public/index.html

Line 31 in 81adbc8

ws = new WebSocket("ws://127.0.0.1:80/echo"); //address to connect to, /echo triggers go echo function

Hi. Same problem. I'm trying to add 127.0.0.1:80 and my local 192.168.1.3 from ipconfig
What another address if runing local?
Thanks.
Chrome:

@AlinaDovbysheva Hi! I did find a typo that shouldn't affect anything, but I went ahead and updated index.html, so definitely try that. Let me know if it works.

Maybe some misstakes on my side.
Is it correct:

1. index.html ws = new WebSocket("ws://127.0.0.1:80/echo")
2. main.go
   udpListener, err := net.ListenUDP("udp", &net.UDPAddr{
   IP: net.IP{0, 0, 0, 0},
   Port: 80,
   })
   .....
   settingEngine.SetNAT1To1IPs([]string{}, webrtc.ICECandidateTypeHost)
   ......
   err = http.ListenAndServe(":80", nil) //Http server blocks
   ?

Hmmm, that all looks fine. Is the go program showing that more ICE candidates are being sent? It will look like this in the terminal: {candidate:4212933298 1 udp ... }

In index.html pc.iceConnectionState does not go to the connected state

problem with chrome
I launched in Edge and its working
Now I'm trying to figure out why it doesn't work in chrome

[wawesomeNOGUI]

Ohh interesting, yeah it is always tricky to work out bugs between different browsers :D It works for me in chrome version 102.0.5005.115, are you running the same version of chrome?

[AlinaDovbysheva]

The same 102.0.5005.115
