Hi there Tajuddin (and everyone else), Would you be kind enough to go through step by step the process you went through to solve your problem.
I have gone through all the installation processes of installing everything on an AWS EC2 instance (with Ubuntu 18.04.2 LTS). At first glance everything seemed to be working fine until I realized that when 2 users were logged on in a room, they could see their own camera but could not see the other participants screen (this applies to audio also). At first I thought this might be down to how I installed everything but having read most (if not all the treads), I came across the following query which suggests a Turn Server is required... ( https://issues.apache.org/jira/browse/OPENMEETINGS-2066
 ) According to the Kurento documentation ( https://doc-kurento.readthedocs.io/en/6.10.0/user/installation.html ) If Kurento Media Server, its Application Server, or any of the clients are located behind a NAT <https://doc-kurento.readthedocs.io/en/6.10.0/glossary.html#term-nat>, you need to use a STUN <https://doc-kurento.readthedocs.io/en/6.10.0/glossary.html#term-stun> or a TURN <https://doc-kurento.readthedocs.io/en/6.10.0/glossary.html#term-turn> server in order to achieve NAT traversal <https://doc-kurento.readthedocs.io/en/6.10.0/glossary.html#term-nat-traversal> . I tried the suggest TURN settings using NUMB (after registering a user name and password), but with no joy, still have the same problem. Finally on a separate matter I noticed there are 9 versions of Alvaro's instructions for setting up openmeetings on Ubuntu 18.04 LTS - versions 1 to 7 make reference to DOCKER.... 8 and 9 don't. Excuse my ignorance but does that mean it is no longer require. All versions contain the same date (25-3-2019). Any help would be appreciate. All the best. Denis
