No video, no sound when on different Network

Hi,

I have stable install of jitsi on a VM in my internal network (Follow quick install instruction) on Debian 10.3 with Firewall NAT.

No problem when users are in the same network (internal network ou wifi network at home)
But no sound and no video when users are from different networks or jitsi android app.

Firewall:
NAT forward ports 10000udp, 80,443,4443tcp

netstat :

Thank you for help !

Are these IP addresses reachable to endpoints in other networks?

PUBLIC_ADDRESS=194.214.134.90 is reachable from outside.
LOCAL_ADDRESS=172.30.2.90 only on local network, at work.

I am having the same issue,
quick installation
just for a LAN, without domain; just the URL to connect, just for the LAN users (even without internet access)
I have made the quick install, and put my local address: 192.168.0.11
I have created at: /etc/ssl both: 192.168.0.11.crt and 192.168.0.11.key

When I connect from the devices of the network, it only shows my own video, not the other ones. I mean, clients only see thereselfves. The other ones appears as if the had they camera and micro set off (but they hadn´t)

Installation is on a ubuntu client (18) that I have downloaded this morning
I also tried on an ubuntu server (18)

The chat and createRoom works perfectly between all the clients connected

On my firewall log, I can see https 443 tcp only.
No connection on 10000 udp or 4443 tcp.
any idea ?

And nginx log
2020/04/21 17:50:47 [error] 527#527: *817 connect() failed (111: Connection refused) while connecting to upstream, client: yyyyyyyyy, server: 0.0.0.0:443, upstream: “127.0.0.1:4445”, bytes from/to client:0/0, bytes from/to upstream:0/0

I Think that my corporate Firewall IDS is very restrictive.
I’m trying to add rules for protocols.

Withch protocol is used by Jitsi Meet ?
XMPP, SIP, P2P, SRTP, OSCAR… ?

I have the same issue, its the default Debian-Package, the problem are the file rights for:

-rw------- 1 root root 3272 May 4 11:46 /etc/jitsi/meet/

Its not perfect, but I changed them with:

chmod 644 /etc/jitsi/meet/hostname.key

After a restart

/etc/init.d/jitsi-videobridge restart

Then the turnserver ist listening on 4445

netstat -tulpen | grep 444
udp 0 0 127.0.0.1:4445 0.0.0.0:* 111 14742 770/turnserver

The same here, I find it strange, to use an IPV4-Address for anUDP6 connection, there is no udp-Entry for the port 10000 in the Table.

I tried to edit /etc/jitsi/videobridge/sip-communicator.properties it makes no difference:
diff /etc/jitsi/videobridge/sip-communicator.properties /etc/jitsi/videobridge/sip-communicator.properties.ori
2,7c2
< #org.ice4j.ice.harvest.STUN_MAPPING_HARVESTER_ADDRESSES=meet-jit-si-turnrelay.jitsi.net:443
< org.ice4j.ipv6.DISABLED=true
< org.jitsi.videobridge.SINGLE_PORT_HARVESTER_PORT=10000
< org.jitsi.videobridge.DISABLE_TCP_HARVESTER=true

Thank you for your answer.

Yes, this is strange for udp6 :10000.

however I am also thinking of internal / external DNS problems and hostname or /hosts.

Currently, I installed the machine in DMZ with a Public IP.
Everything works except with the android application…

I also did not mange to use the own Server direct from the App.
It only worked by first opening the page in the browser and then using the link: “Continue to the App”, after I installed the App on Android.
