negotiation failed error

[alankeny]

I had galene-0.1 working back in January. I recently upgraded to the latest code on GitHub, but now I can't start any audio, video, or screen sharing. I've tested with Firefox, Chromium, and Safari.

After I click on the Ready button and allow the camera and microphone, I get the error message, "The Server said: negotiation failed" in the browser. On the server I get the error, "gotOffer: SetRemoteDescription called with no ice-ufrag".

I get the same errors on galene-0.2. If I go back to version 0.1, everything works again.

Galene is configured to use a TURN server running Coturn on a Digital Ocean droplet. Coturn's use-auth-secret option is commented out, so I did not specify "credentialType": "hmac-sha1" in the ice-servers.json file.

Do I need to change my configuration in some way for version 0.2 and later?

Thanks.

What's in Galène's log?

The only log output I've seen so far is the line that starts with gotOffer: gotOffer: SetRemoteDescription called with no ice-ufrag

Let me know if there's anything I should do to increase the log output.

What browser is that? Could you please let me know what the following patch displays?

diff --git a/rtpconn/webclient.go b/rtpconn/webclient.go

I've tested with Firefox and Chromium on Linux and Safari on MacOS. I'm getting the same error in all three.

I got an empty string in the log at first, so I modified your patch like this:

log.Println("---")
log.Println(m.SDP)
log.Println("---")

and I got the following output:

Cannot reproduce, sorry. I suspect this was due to a mismatch between the server and client versions. Please reopen if you can reproduce it.
