Error host unknown in videobridge

hello everyone,

Am in Ubuntu 18.04 and i follow all the steps of Quick install. With 2 participants it works great, but if more the video and audio didn’t i don’t know why. It’s more then 12 days that i try to find anything and i have installed 8 times jitsi meet but no way, always don’t work. All ports are open in firewall machine and nat is correct.
So i decide to post this because I would like to have any help from community. in jvs log i have this error

host-unknown,, port:5347
org.xmpp.component.ComponentException: host-unknown

my config videobridge
Jitsi Videobridge settings

# sets the XMPP domain (default: none)

# sets the hostname of the XMPP server (default: domain if set, localhost otherwise)

# sets the port of the XMPP server (default: 5275)

# sets the shared secret used to authenticate to the XMPP server

# extra options to pass to the JVB daemon
JVB_OPTS=" --apis=rest,xmpp "

# adds java system props that are passed to jvb (default are for home and logging config file)
JAVA_SYS_PROPS=" -Djava.util.logging.config.file=/etc/jitsi/videobridge/"

Thx you for advance for any little help!


could you solve your issue? are you running jvb from source?
