Hello Maxim, This line was in an openmeetings.log: DEBUG 10-08 09:23:39.469 o.a.o.c.r.KurentoHandler:152 [ntLoopGroup-3-1] - JsonRpcWsClient disconnected from ws://127.0.0.1:8888/kurento because Channel closed.
Is this the problem? The manual states the applicationContext.xml should be edited to kurentoWsUrl="ws://127.0.0.1:8888/kurento" The OM-Server is an intern server, so there is no need to go through a firewall. So I don’t know, if I even need this coturn-stuff. You asked: Am I right thinking you get "Connection to Media server has been established" and then "Media server connection for user test is disconnected, will try to re-connect" ? That’s right, it works fine for about one minute. I couldn’t find any turnserver-logs (/var/log/turnserver is empty). Here is some more of the openmeetings.log: DEBUG 10-08 09:11:02.651 o.a.o.d.u.AuthLevelUtil:40 [nio-5443-exec-8] - Level ADMIN :: [GRANTED] DEBUG 10-08 09:11:02.657 o.a.o.d.u.AuthLevelUtil:40 [nio-5443-exec-8] - Level ADMIN :: [GRANTED] DEBUG 10-08 09:11:02.657 o.a.o.d.u.AuthLevelUtil:40 [nio-5443-exec-8] - Level ADMIN :: [GRANTED] DEBUG 10-08 09:11:02.747 o.a.o.w.c.OmWebSocketPanel:74 [nio-5443-exec-8] - pingTimer is attached DEBUG 10-08 09:11:02.758 o.a.o.w.p.MainPage:102 [nio-5443-exec-8] - renderHead:: newAreaBehavior DEBUG 10-08 09:14:59.712 o.a.o.s.q.s.ReminderJob:93 [Bean#0_Worker-4] - Rss disabled by Admin INFO 10-08 09:23:39.468 o.k.j.c.JsonRpcClientNettyWebSocket:275 [ntLoopGroup-2-1] - channel closed INFO 10-08 09:23:39.468 o.k.j.c.JsonRpcClientNettyWebSocket:275 [ntLoopGroup-3-1] - channel closed DEBUG 10-08 09:23:39.469 o.a.o.c.r.KurentoHandler:152 [ntLoopGroup-3-1] - JsonRpcWsClient disconnected from ws://127.0.0.1:8888/kurento because Channel closed.

I used the manual: Installation of Apache OpenMeetings 5.0.1 on Ubuntu 20.04 lts. Step by step. in my last mail there was a typo, actually it’s /opt/501, not /opt/504. I downloaded: sudo wget https://downloads.apache.org/openmeetings/5.0.1/bin/apache-openmeetings-5.0.1.tar.gz Is that the problem? Do I have to use a newer version of OM? As KMS I use Docker, just like in the manual. I am testing on Firefox ESR 68 (latest update) and Windows 10 Enterprise 1909. Yes, there are some logs, which ones would be the most helpful to analyze?

What KMS version are you using What browser/OS are you using for testing? Any errors in server logs (logs/openmeetings.log and/or KMS logs) On Thu, 8 Oct 2020 at 21:33, Ninnig, Alexander <alexander.nin...@rechnungshof.rlp.de<mailto:alexander.nin...@rechnungshof.rlp.de>> wrote: Hello, I'm sure this has been answered before, but I couldn't make it work yet. I just set up a new OpenMeetings-Server (Ubuntu Server 20.04 LTS, OM 5), using the official manual. After entering a room, Webcam/Micro work fine for about 1 minute, then there is no picture/no sound ("Media server connection for user test is disconnected, will try to re-connect"). After that, I can turn off/turn on webcam/micro, using the OpenMeetings-buttons, but again it will work for only about one minute. My first mistake was, not to setup Coturn, because I somehow thought, I wouldn't need the second manual. So I installed Coturn, using the second manual, and I thought, that was it, because after entering a room, I saw: "Connection to Media server has been established", which I don't remember seeing before. But still: no webcam/mic after about 1 minute. Same error. My scenario: It's an intern OpenMeetings-Server, so I don't have to go through any firewall. We have about 200 users, who don't use OM all at once, so we don't need any high-perfomance-tweaks. As certificate, I use a real domain-certificate from an intern Microsoft domain-CA. I didn't follow the manual here, but just changed the /opt/open504/conf/server.xml, changing the lines [that's the way, someone suggested it here in the mailinglist, as I was testing OM5 a few months ago]: <Connector port="5443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" SSLEnabled="true"> <SSLHostConfig> <Certificate certificateKeystoreFile="conf/localhost.jks" certificateKeystorePassword="openmeetings" certificateKeystoreType="JKS" certificateVerification="false" sslProtocol="TLS" type="RSA" /> </SSLHostConfig> </Connector> into <Connector port="5443" SSLEnabled="true"> <SSLHostConfig> <Certificate certificateFile="/etc/myfirm/myserver.pem" certificateKeyFile="/etc/myfirm/key.pem" certificateChainFile="/etc/myfirm/chain.pem" sslProtocol="TLS"/> </SSLHostConfig> </Connector> EXCEPT for that, I think I followed the manuals thoroughly. I got LDAP working, HTTPS seems fine. I just can't get a stable webcam/mic. If you think, my certificate-deployment could be the problem, I would change that (following the new manual). If not, can you give me some advice on where to look? I can post logs, if needed. Best regards, Alex -- Best regards, Maxim -- Best regards, Maxim
