Re: Media server connection is failed, will try to re-connect

2023-03-28 Thread Maxim Solodovnik
According HTTPD config:

everything looks great

Locations like `` was required by Flash version and
can now be dropped

Such config require `$OM_HOME/conf/server.xml` modification, but I'm
sure you did it

You can send me private email, and I'll try to check if your server works for me

Re: Media server connection is failed, will try to re-connect

2023-03-28 Thread Thomas Scholzen



Hi Maxim,

the size of the backup was ~ 4 GB. When the upgrade failed, I 
reinstalled OM 7.0.0. When having problems, I also reinstalled coturn & 
docker (plus km). When all failed I asked you ;-). The (re) installation 
was done on the same server on which OM 6.0.0 was running before.


Kind regards

Hi Maxim,

thanks for the fast response. I used the command line for migration, and 
it did not work (restoreing backup just hangs forever). But no problem 
there, I should clean up the installation anyway ;-).


My server is not a VM but bare metall. So I have to live with the

As you suggested, I will try kurento without docker and see how it goes.

BTW "kurento via docker" might be not necessary in your case
KMS7 was released and it natively supports Ubuntu 20 :)

Media server connection is failed, will try to re-connect

2023-03-28 Thread Thomas Scholzen



Hi Maxim,

I just migrated from OM 6.00 to 7.00. After the upgrade did not work 
(too much stuff in the backup) I went for a fresh installation. I 
installed OM 7.0.0, kurento via docker and coturn. However, I get "Media 
server connection for user  XXX is failed, will try to re-connect" every 
2 to 15 seconds, depending on the client and location. When the internet 
is routed via VPN to the server that runs OM, there are no problems. OS 
Ubuntu 20.04
So I suspect an issue with the turnserver. With OM 6.0.0 this setup went 
fine, so there is probably some kind of misconfiguration.


"$ docker logs kms" gives me:

"KurentoWebRtcEndpointImpl 
WebRtcEndpointImpl.cpp:609:WebRtcEndpointImpl: TURN server not found in 
config; remember that NAT traversal requires STUN or TURN"


In /etc/turnserver.conf I have:
  use-auth-secret
  static-auth-secret=7xxx
  realm=testexample.de
  stale-nonce=0
  log-file=/var/log/turnserver/turnserver.log
  syslog

In webapps/openmeetings/WEB-INF/classes/openmeetings.properties I have:

   kurento.ws.url=ws://127.0.0.1:/kurento
   kurento.turn.url=xxx.yyy.zzz.aaa:3478
   kurento.turn.user=
   kurento.turn.secret=7xxx
   kurento.turn.mode=rest

Because I run also other services on this server SSL is done via port 
4443 with a proxy to localhost:5080/openmeetings (see attached apache2 
virtual host config). This makes it a bit complicated, but it was 
working flawless with OM 6.0.0


I Would appreciate if you could give me a hint how to debug this.

Best regards
