@Tajuddin and anybody else that can help. Tajuddin, I have been "off grid" for some time and apologies to those I have not been able to be in contact with recently.
Hopefully you might be able to provide me with some help. And please forgive me if I haven't seen a previous, solution or comment that might help me with this problem. I am adding to a thread that was created by in May of last year (2019)... and given the whole Coronavirus issue, I have been forced to look into a working version of OpenMeetings, on an AWS instance... before things turn to s#it on my side... and when I say "s#it"... it is breaking my heart. I set up OM some time back and everything seem to run beautifully.... a few glitches with uploading ( I understand there have been some improvements).... but after increasing ram and cpu speed things got to an acceptable level (running OM 5 - M2). As you can appreciate, due to recent events, I have needed to revisit the whole online approach of things and have ran into the following problem: (Tested with me and a few others students on a "one to one" basis) When I am initially in a room... everything works as expected, I am able to move from whiteboard to whiteboard and demonstrate a great class, with audio, video, pdfs and so on.... but suddenly my audio and video is disconnected... I can still see and hear the other participant... but they can't see or hear me.... I refresh the page... and everything continues as normal for a few mins... and my audio and video is disconnected again. This "seems" to be Kurento related only (I assume) as I can still interact with everyone via whiteboard etc. Based on previous messages that you may see below with Tajuddin, this is probably related to having a AWS EC2 virtual server... using a "NUMB" "turn server" (details below in a previous message). Is there anyone out there that can explain in simple terms... "apples and bananas"... what I should be doing in order to get things running to at least a minimal acceptable level? For reference, I have the following setup (I know that some recommendations will be to upgrade to OM 5.03... but I am still curious as to the "why" regarding my current setup and situation). OM Version 5.0.0-M2-SNAPSHOT Revision 85daa3b Build date 2019-05-13T16:53:23Z Kurento 6.10.0 bionic kms6 Ubuntu 18.04 Once again, if if hasn't been clear... in this email or others... I am a simple teacher that thought by opening up a AWS EC2 instance, I could make a difference... and now even more, given the state of affairs... I am bumbling over my owns steps trying to get something working... I think I have even knotted myself up in confusion. I would appreciate any help on this... @Tajuddin @Maxim and at anybody else. If you can.... please... get back in touch with constructive comments or suggestions... I know you all have a lot going on during this time and I wish you all the best and good health... I am more than happy to make myself a personal ambassador of OM after all of this! All the best. Denis On Tue, May 28, 2019 at 4:04 AM Denis Noctor <denisnoc...@gmail.com> wrote: > Good man Tajuddin.
