Connection to media server failed
Hello,
I keep getting an error message for connection to media server. It says connection to media server for user firstname secondname failed, trying to reconnect. I get a permission request from the browser to access camera and mic, and after allowing permission I get the connection error message again and again all the time.
The board and drawings/writing are visible to the other side correctly, but no voice or camera, and no screen sharing or recording.
The KMS is running and accessible, but why the connection keeps failing and resetting all the time?
Please share your experience.
Thanks.

...yesterday i've installed OM 5.0.0-M4 on Centos 7 in a VPS,with few
resources, and it works everything.I've following the tutorial step by
step but putting:
SELINUX=disabled
Here are the commands to open the ports in firewalld Centos 7:
service firewalld start
sudo firewall-cmd --zone=public --add-port=3478/tcp --permanent
sudo firewall-cmd --zone=public --add-port=3478/udp --permanent
sudo firewall-cmd --zone=public --add-port=5443/tcp --permanent
sudo firewall-cmd --zone=public --add-port=8888/tcp --permanent
sudo firewall-cmd --zone=public --add-port=49152-65535/udp --permanent
service firewalld restart
...also must be open in the router.
Restart coturn:
systemctl restart coturn.service
The rest maybe Maxim can help you.

I figured out why the screen is recorded as mirror, it's only when I choose to share the browser window, because the browser settings in right to left. It works fine when I changed the browser to English, so it was a browser issue.
How can I do recording without screen sharing? Why it's always necessary to share something so that I can record? What if I want to record the board and voice only?
Also what do you think about creating a watchdog for monitoring COTURN/KMS and restart both if down? How to do that?

Thank you, this makes it work.
However, when I tested the recording, it's mirror of the screen, not direct shot, I mean it's opposite direction, not readable. What could be the reason causing this?
Also, the media server connection is sometimes successful and sometimes not, which makes it necessary to restart the KMS and OM. How can I make sure it restarts automatically in case of failure, not requiring me to stop/start it from command line?
