Hi Herald,

Can you post the output of

  

  sudo bbb-conf --check

and

  

  dpkg -l | grep bbb

and

  sudo apt-get install -f

[Fred Dixon]

Can you try installing BigBuleButton + SSL + HTML5 with bbb-install.sh, see

  https://github.com/bigbluebutton/bbb-install

which can automate the installation of the HTML5 client.  Let us know if that has the same issue.

Hi Fred,
Did it on our test server but no change in behavior. (https://testhub.integralepraxis.at)

In the mean time I installed Kurento on both life and test system manually. Works fine starting and stopping with bbb. No issues.

Hi Fred,

I did a manual install straight from their repo:

REPO="xenial" # KMS Release - Ubuntu 16.04 (Xenial)

echo "deb http://ubuntu.kurento.org $REPO kms6" | sudo tee /etc/apt/sources.list.d/kurento.list

wget http://ubuntu.kurento.org/kurento.gpg.key -O - | sudo apt-key add -

sudo apt-get update

sudo apt-get install kurento-media-server-6.0

I also installed bbb-webrtc-sfu from your repo manually and ended up with following status:

bbb-conf --status

red5: active
tomcat7: active
nginx: active

freeswitch: active

redis-server.service: active
bbb-apps-akka: active
bbb-transcode-akka: active
bbb-fsesl-akka: active
mongod: active
bbb-html5: active

bbb-webrtc-sfu: active
kurento-media-server-6.0: active

All works fine now but sip. Checking out https://testhub.integralepraxis.at/check/ gives you an idea. Now I have the same check report a guy has posted in this forum at "RTMP sip app: NetConnection.Connect.Failed: undefined".

Cheers Harald

Hi,

> In the mean time I installed Kurento on both life and test system manually. Works fine starting and stopping with bbb. No issues.

Hmmm.  You shouldn't need to do this.  The BigBlueButton project uses it's own packaged version of Kurento.  

Can you post the output of

# dpkg -l | grep kurent

Her'es what it shows on one of our test servers

# dpkg -l | grep kurent

ii  kurento-media-server-6.0              6.7.0.xenial~20170813003033.1.6ebaa27     amd64        Kurento Media Server

Hi Fred,

My version looks like

dpkg -l | grep kurento

ii kurento-media-server-6.0 6.7.0.xenial~20170813003033.1.6ebaa27 amd64
Kurento Media Server

Is there any customization done in your version? If so I can Uninstaller my version, delete the repo lists of Kurento and start over installing from your repo.

Cheers Harald

Hi

It looks like you have the same version from our repository, so there is nothing to uninstall.  

> RTMP sip app:           NetConnection.Connect.Rejected:

> RTMPT sip app:          NetConnection.Connect.Failed: undefined

Does your server have a single public IP address, or it behind a firewall with an internal/external IP address?

Can you check the values in

  /etc/bigbluebutton/nginx/sip.nginx

it's going to be one of 

proxy_pass http://xxx.xxx.xxx.xxx:5066;

or

proxy_pass https://xxx.xxx.xxx.xxx:7443;

For whichever one, check the output of

 netstat -ant | grep 5066

or

  netstat -ant | grep 7443

and the resulting IP address should match that defined in sip.nginx.

Regards,... Fred

Hi Fred,

netstat -ant | grep 7443

Perfect match it seems. Cheers Harald

[Chad Pilkey]

Don't worry about the sip app failing in /check. It hasn't been updated to match new properties that are required on connect. Also, the RTMP SIP is not the same as sip.nginx which is for WebRTC.

[Chad Pilkey]

I just pushed a fix for the SIP app check and once it's pushed to the public repo you should see it succeed again.

[Harald Kastner]

Thanks Chad,

I'll wait for the repo update 👍

Cheers Harald

[Harald Kastner]

RTMP sip app:  NetConnection.Connect.Rejected: No scope 'screenshare' on this server.
RTMPT sip app:  NetConnection.Connect.Rejected: No scope 'screenshare' on this server.

That's new indeed!

[Chad Pilkey]

I don't think the public packages have been updated. Our demo server that's based on the public packages still shows the error https://demo.bigbluebutton.org/check/, but our internal staging server does not. It's a pretty low impact issue so a push to public might not be for a bit.

[Fred Dixon]

Hi Harald,

The BigBlueButton HTML5 client is under active development.  Can you do a quick test against

   https://test.bigbluebutton.org/

and let us know your experience.  You can expect an update of the packaging shortly to enable you to install the same version as you see on test.

Regards,... Fred

Hi Fred,

Certainly I tested the HTML5-Client.

First of all it started flawless, selection of audio worked as expected. Starting video/camera worked showing the camera window but brought up two consecutive error messages "Error on sharing webcam". Loading up a new PDF-document seems to work but after finishing loading up everything was messed up. Only the camera window was still visible. No chance to reach any further control element or window. Pushing back in the browser and log in again lead me to the same start up experienced previously (including webcam error messages) but showed up my uploaded document instead of your standard one (small wonder the room was not shut down in the meantime). Browser: Google Chrome for Android 64.0.3282.137

Cheers Harald

[Harald Kastner]

All in all I am impressed how far you have come with the HTML5-client. Still not flawless I cannot use it for daily routine but with a client needing an urgent meeting I would introduce it anyway because problems if any seem to occur on moderator's side, client's side looks pretty stable.

Cheers Harald again

Btw: The camera video is not stoppable anymore after starting it, maybe something to do with the error messages?
