Media server connection for user test is disconnected, will try to
re-connect
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

Hello Alex,
this is definitely not SSL certificate
What exact OM version are you using (the path is /opt/open504 so I guess it
is 5.0.0-M4 ?)
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)

Re: TCP socket error: Connection reset by peer 195.54.161.237:16836 (

Posted by Maxim Solodovnik <so...@gmail.com>.
AFAIK "Connection reset by peer" means the connection was closed by the
user or by the network error
why do you think this is a problem?

Re: Media server connection for user test is disconnected, will try

Posted by Maxim Solodovnik <so...@gmail.com>.
The logs need to be checked are
1) openmeetings.log (openmeetings.<date>.log if <date> != today)
2) KMS logs (should be available if docker was started in "interactive"
mode, or you can mount docker's /var/log to some local folder)
3) TURN logs
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" ?

Yes, your KMS is down

to re-connect
Posted by "Ninnig, Alexander" <Al...@rechnungshof.rlp.de>.
Hello Maxim,
thank you so much for all your help (not only with this issue).
Please consider this issue as closed: our group policies (GPO) seem to be the problem.
I didn't think of that, because of the weird behaviour (stopping after one minute).
If it hadn't been working right from the start, I may have guessed it.
Anyway, I moved my active directory accounts to organization units without group policies: webcam is stable since about half an hour.
Sorry for bothering you here, Maxim.
To all you folks out there: in case you are using Firefox (or other browsers) in a business-environment with group policies, you might wanna check that.
Best regards,
Alex
PS: The new OpenMeetings looks very nice! Nice layout, good translation (german), and it works really well in Firefox (Screensharing, Camera, Microphone, etc.).
Also, I had no problems installing OM5, deploying a certificate, configuring and importing LDAP so far.
Really well done!

Yes, your KMS is down
so no audio/video anymore
please check if Docker is up and running and KMS is alive inside of it

since you are using local docker this should be correct URL

most probably not
Multimedia server is down so no broadcasting

it seems KMS is able to work for 1 minute
you have to check what is wrong with it

AW: Media server connection for user test is disconnected, will try
to re-connect
Posted by "Ninnig, Alexander" <Al...@rechnungshof.rlp.de>.
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:

The logs need to be checked are
1) openmeetings.log (openmeetings.<date>.log if <date> != today)
2) KMS logs (should be available if docker was started in "interactive" mode, or you can mount docker's /var/log to some local folder)
3) TURN logs
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" ?

Hello Maxim,
thanks for your response.
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? Openmeetings.<date>.log?

Hello Alex,
this is definitely not SSL certificate
What exact OM version are you using (the path is /opt/open504 so I guess it is 5.0.0-M4 ?)
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)

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
