Hi there Maxim, First of all, thanks for all your efforts to date. I have noticed via the forum you have been fighting fires answering lots of emails and queries and I salute you.
I decided it best to take a few days before answering you email after upgrading everything to *OM 5 M3* (as per Alvaro’s instructions, which are great). Version 5.0.0-M3 Revision b739f87 Build date 2019-12-11T11:42:09Z Connect direct Using Chrome browser (as are my students) Version 80.0.3987.149 (Official Build) (64-bit) AWS E2 Instance Ubuntu 18.04.4 LTS(FULL SPECS AND PORTS OPEN AT THE BOTTOM OF EMAIL https:// with AWS Certificate I installed everything as per the instructions and setup up a “*Turn server*” account with *NUMB* (*http://numb.viagenie.ca/ <http://numb.viagenie.ca/>*) as recommended by as per Tajuddin Bennur’s https://mail-archives.apache.org/mod_mbox/openmeetings-user/201905.mbox/browser and made the following changes (*ONLY*) as per the recommendations in: /etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini uncommenting and adding: *turnURL=USERNAME:[email protected]:3478 <http://USERNAME:[email protected]:3478> *In /opt/openmeetings/webapps/openmeetings/WEB-INF/classes/applicationContext.xml The only changes I made were similar to those above (though I tested everything before adding these changes are the following – but honestly, I haven’t really noticed any difference: <bean id="kurentoHandler" class="org.apache.openmeetings.core.remote.KurentoHandler" init-method="init" destroy-method="destroy" p:kurentoWsUrl="ws://127.0.0.1:8888/kurento" p:checkTimeout="10000" p:watchThreadCount="10" * p:turnUrl="158.69.221.198:3478 <http://158.69.221.198:3478>"* * p:turnUser="USERNAME"* * p:turnSecret="PASSWORD"* p:turnMode="rest" p:turnTtl="60" p:objCheckTimeout="200" /> The end result is: Whiteboard for my uses is working beautifully, conversion process is working beautifully, drag and drop of audio and video is working beautifully… though I tried to upload a 59 M file and everything seemed to hang for a while so I cancelled the upload… but appeared in my online files later on… probably more ram and CPU speed will deal with this.. no major problem as I re-uploaded a smaller vid file and it did the job. In all everything is working well except for the following: When enter a room, I can see and talk to a student ( and vice versa) very well. Audio quality is good and cam settings are as expected. This is something I couldn’t do in the past without the recommended Turn Server settings as mentioned about. *PROBLEM:* When I enter a conference room( first), and then when 2 students enter the room… after some time my cam box disappears from my screen. I am still in the room… I can still hear and see everyone else interacting with each other – but they can’t see or hear me. When I click on the cam and camera icon everything continues as normal until it happens again. Worth noting – I am the moderator. However, if I don’t turn on my camera and microphone again… after some time the same thing happens to the first user that entered the room after me… and so on. Apart from that everything is working really well. I remember some time back that a similar problem occurred with a user in the past but I can find anything in the user forums. Again important to note that I am using a TURN SERVER setup as mentioned above…. I have NOT implemented COTURN as I am under the impression TURN overrides COTURN.(?). Any suggestions / help as to what might be causing this?
