SPECIFICATION OF THE ENVIRONMENT: Main server: It is a VPS. Runs as a guest in a virtual environment. Ubuntu 18.04.4 LTS (GNU/Linux 4.19.0-6-amd64 x86_64)
INSTALLED APPLICATIONS under the UBUNTU server: Installation OpenMeetings 5.0.0-M4 on Ubuntu 18.04 LTS.pdf Installation SSL certificates and Coturn for OpenMeetings 5.0.0-M4 on Ubuntu 18.04.pdf I used these two documents above and installed everything including the CoTURN server and the "letsencrypt.org" free SSL certificate. The SSL certificate was installed manually, I did nor used the automatic installation method. No firewall is activated on the Linux server. INSTALLED APPLICATIONS/CLIENT MACHINES: - operating systems: Windows 10 - Google Chrome is up to date (Version 81.0.4044.138 (Official Build) (64-bit)) - proxy: no SPECIFICATION OF THE PERFORMED TESTING: Two user are present in the same room. One is sitting in Greece the other one in London. We used the following functions: - video/audio communication - screenshare Duration of the test: one hour DESCRIPTION OF THE PROBLEM: Audio/video connection suddenly stoped abou ten times within the one hour. The other user cannot hear/see me or the other way. Connection can be reestablished with EXIT and then entering the room again. If I do same testing using two machines on the same local network running the same client, the video/audio communication is very stable.

If I use the client machines on the local network, no "error 401: Unauthorized" message and video/audio stable. QUESTIONS: 1. The turn server log has no date stamp so I cant determine the action in the application. Should I modify the COTURN server source and recompile it? 2. Is "error 401: Unauthorized" a legal message? Where can I find info about this? 3. Has anyone the same problem? 4. Should I set anything in the Chrome client if I want to use it with the CoTurn server? 5. I have several hours testing capacaty every week. Could you give me any hint how to proceed? I want want to find out why is this version so unstable. It is practically unusable. By the way, I like OM. Thank you. jox (REF: 2020-05-13-13-43-26) Search Results Web result with site links
