User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36

Steps to reproduce:

When using WebRTC via proxy server ICEServer gathers fails. As far as i know it only happens in windows 8, 10 but not in windows 7.


Configure Firefox to use a proxy server. 
Test the Trickle ICE funcionality via https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/
In this page remove default sturn server, and add a turn server in the following way: "turn:xxx.xxx.xxx.xxx:443?transport=tcp" and authentication info.
Click on 'Gather Candidates'




Actual results:

The result is 

Time	Component	Type	Foundation 	Protocol	Address	Port	Priority
0.003	1	host	0	UDP	192.168.2.20	49841	126 | 32512 | 255
0.003	2	host	0	UDP	192.168.2.20	49842	126 | 32512 | 254
1.642	Done


Expected results:

The result without proxy is

Time	Component	Type	Foundation 	Protocol	Address	Port	Priority
0.003	1	host	0	UDP	192.168.2.20	53877	126 | 32512 | 255

Might be the same issue as in bug 1237299.

Could you please check if the problem is fixed when you try it with the latest Nightly (https://nightly.mozilla.org/)?

Tested with 46.0a1 (2016-01-17) and not working, same problem.

Actually it works sometimes (1 in 15 aprox).
Stable version (43.0.4) is not working at all.

Do you need any log file?

FYI the error in your signaling log is misleading and should not longer show up in your logs in Nightly.

From the logs you attached I suspect that we can't handle the response from the proxy you use. I uploaded a patch which adds more logging to our proxy code. Once the try build here:
  https://treeherder.mozilla.org/#/jobs?repo=try&revision=8ca70b302407
has finished, could you please download the binary and try again and upload the log again? 
I only need the aboutWebrtc log part.

Hi,
We were very interested in this report. We have tried 47 beta Firefox version but we could not see our TURN as a candidate unfortunately. Is somebody made it worked? thanks. Arnaud
