Installation of jitsi-meet not working

Hi Guys,

after 2 days of reserching and trying to install jitsi-meet successfully, I´m writing this post.

Its running on an external hosted Ubuntu 18.04 Root Server, so there is no need for FQDN.
Im able to access the server with my webbrowser with https and I´m also able to create a meeting.
But when entered the meeting I cant use any of the funcionalitys and also dont get moderator privileges. I can´t even chat and after some seconds I get a connection lost.

80 and 443 TCP are open and 10000 UDP aswell.

I did my installation with this quick install guide: github com/jitsi/jitsi-meet/blob/master/doc/quick-install.md

After it didn´t work I purged the installation as mentioned here: community.jitsi org/t/not-working-for-more-than-2-people-in-the-room/18821/75

After an full reinstall it is still not working.
So I also tried this:

vim /etc/jitsi/meet/vc.server.com-config.js
Change:
// requireDisplayName: true,
to
requireDisplayName: true,
vim /etc/jitsi/jicofo/sip-communicator.properties
add:
org.jitsi.jicofo.auth.URL=XMPP:ub18-meinserver
service prosody restart && service jicofo restart

Nothing changed, even after an full server reboot.

I hope you guys find the mistake.
I get some Java exceptions, guess the problem is somewhere over there.
The only real error (without the java exceptions) is following: “Error binding encrypted port for https: No key present in SSL/TLS configuration for https port 5281”. But Damencho allready mentioned in an other thread, that this can be ignored.

Info: Its pretty anoying to only be allowed to use 2 links as new user… ^^
Made it pretty hard to post it.

Firewall blocking port 5222 on localhost?

Hi, thank you for your fast reply!

Ive checked it now and unfortunately it wasn´t the problem.
Port is open and working.

netstat -tulpen
Proto Recv-Q Send-Q Local Address           Foreign Address         State       User       Inode      PID/Program name
tcp        0      0 0.0.0.0:5222            0.0.0.0:*               LISTEN      112        123722     18952/lua5.1

nc -v localhost 5222
Connection to localhost 5222 port [tcp/xmpp-client] succeeded!

Currently I have no Firewall rules on the server itself.
There are also currently no hosts.allow and hosts.deny

Still no clue…
The only reason I can imagine right now is, that there is an error inside of the java code, because the port is open and listening.
But why am I the only one with this problem… :confused:

Hope someone has an idea :slight_smile:

Does telnet 127.0.0.1 5222 also succeed ? (you should get “Connected to 127.0.0.1.”)
Are you sure your potential local firewall allow all traffic on lo interface ?

as I mentioned, port is open.

telnet 127.0.0.1 5222
Trying 127.0.0.1…
Connected to 127.0.0.1.
Escape character is ‘^]’.

Yes, all local traffic is allowed, because I have no local firewall, only an external one.
And it doesn´t work too, when I turn off the external one.

But thanks for the reply!

I’m also experiencing the same issue with a clean Lubuntu 18.04 installation. Locally I am able to connect completely but externally I can not establish Video or Audio connections. I also have the same Exception in the /var/log/jitsi/jvb.log

Exception in thread “Thread-5” java.lang.IllegalArgumentException

in the /var/log/jitsi/jvb.log

Could it be related to this issue: https://github.com/jitsi/jitsi-videobridge/issues/1162
Or it’s fix: https://github.com/jitsi/ice4j/pull/193

Running on a DynamicIP I think that I need the StunHarvesters working, if your externally hosted server has a fixed IP then specifing it explicitly might fix the issue for you but not the issue you found!

as you said it’s very unlikely that you could be the only one with this bug.
As you have a problem in the java parts, not in the javascript, it’s unlikely that the problem could be in the jitsi-meet configuration, it’s the java part config that you should post; specifically the config files in jicofo and videobridge2 directories under /etc/jitsi, and also /etc/hosts

Finally I managed to run it.
So my steps were now: (Strong printed = your own FQDN)

  1. apt --purge remove jicofo* prosody* jitsi* apache2 nginx*
  2. apt install locate
  3. updatedb
    then remove all files you find with “locate jitsi”, “locate jicofo”, “locate prosody”
  4. cat /etc/passwd && cat /etc/group # delete all users and groups, related to jitsi
  5. apt autoremove
  6. apt -y update
  7. reinstall jitsi-meet
  8. vim /etc/jitsi/meet/vc.serverdotcom-config.js
    8.1 change under “p2p” the variable “enabled:” from true to false.
  9. vim /etc/jitsi/videobridge/sip-communicator.properties
    9.1 change this file to look like this

org.ice4j.ice.harvest.DISABLE_AWS_HARVESTER=true
org.ice4j.ice.harvest.STUN_MAPPING_HARVESTER_ADDRESSES=meet-jit-si-turnrelay.jitsi.net:443
org.jitsi.videobridge.DISABLE_TCP_HARVESTER=true
org.jitsi.videobridge.ENABLE_STATISTICS=true
org.jitsi.videobridge.STATISTICS_TRANSPORT=muc
org.jitsi.videobridge.xmpp.user.shard.HOSTNAME=localhost
org.jitsi.videobridge.xmpp.user.shard.DOMAIN=auth.vc.serverdotcom
org.jitsi.videobridge.xmpp.user.shard.USERNAME=jvb
org.jitsi.videobridge.xmpp.user.shard.PASSWORD=yourown, dont change
org.jitsi.videobridge.xmpp.user.shard.MUC_JIDS=JvbBrewery@internal.auth.vc.serverdotcom
org.jitsi.videobridge.xmpp.user.shard.MUC_NICKNAME=yourown, dont change

  1. systemctl restart jicofo && systemctl restart jitsi-videobridge2 && systemctl restart prosody && systemctl restart nginx

I dont know which steps are necessary, but this is what I did.

Now an important info for all people. That tricked me hard!
I have an simple DNS entry to the global ipv4 of the server.
There is no Domain registered for this server in my case.

In my case there were 3 different strings to access the webpage.

  1. https://123.456.789.012 (global IP of the external root Server)
  2. https://mein-server (Alias on DNS Server)
  3. https://ub18-mein-server (Hostname of Server)
    All worked fine until you´ve started an meeting.
    The Java functionalitys worked only at one of those 3 and this is the one I´ve entered at the installation progress of jitsi-meet.
    At the Jitsi installation you get asked for the !hostname!.Actually it means the FQDN.
    In my case ive entered “ub18-mein-server”. So it were only possible to work with this one! Not with the alias or global IP-Address, but because I´m a lazy guy, ive used for testing purposes all time the alias “mein-server”

So what I learned?
Read twice not once, especially when you are not in your native language.

If you have a FQDN for the instance already set up in DNS, enter it there.

Thats written in the jitsi-meet quick install guide…
my bad… but I bet I´m not the first one, that did this mistake ^^

Hope someone can use this to find his own problem.

Hy, on the router are you making port forward for the internal ip of the server??
