Hi,

Ive had a successful BBB session working using 0.91 / ubuntu 14.04 etc wtith bbb-demo and the standard instructions.

Ive been trying to implement SSL, with some success, again following the standard instructions...

My problem seems to be webrtc.

i) https://<hostname>/check give all okay except Webrtc Echo Test amd Webrtc Socket Test both 'hang' with a 'Loading...' message.

- The /usr/share/red5/log/0.0.0.0_access.2016-01-02.log file seems to be successful..

- the red5 error.log file gives a few warnings, and indications, but no clear issues...

The nginx bigbluebutton log file shows a couple of errors..

ii) When I start the demo's I get the following message

Detected the following WebRTC issue: Error 1007: ICE negotiation failed. Do you want to try Flash instead?

Netstat shows lots of 'hung' sockets on port 5080..

Would appreciate any pointers or shared expereince of where I should look next... My hunch in somewhere in the https->Wss->red5 chain, but Im I cant see much/anything to point to the next.

Many Thanks,

Fred Dixon

Hi Gary,

> 192.168.1.85 - - [02/Jan/2016:14:28:20 +0000] "POST /send/8CPVBDZNQPAEO/2 HTTP/1.1" 200 1 "-" "Shockwave Flash"

The POST command triggers when the BigBlueButton client can not talk directly with port 1935.

Do you have a firewall on your server? The ports listed at

http://docs.bigbluebutton.org/install/install.html#before-you-install

should be available. If there is a firewall in play, try (temporarily) disabling it and see if you get a connection via WebRTC.

> Webrtc Check 'hangs' , and 1007 with SSL installation.

For WebRTC error codes in BigBlueButton, see

http://docs.bigbluebutton.org/install/install.html#client-webrtc-error-codes

(The 1007 suggests a firewall is blocking access to UDP connections).

Regards,... Fred
