从日志上看来其根本原因是jicofo没有发现jvb

解决办法很多，大家可以自行试一下那个对自己有用

1. 去掉jicofo的健康检查

org.jitsi.jicofo.HEALTH_CHECK_INTERVAL = -1

1.1重启jicofo

2. DNS解析问题
   清除DNS缓存

systemd-resolve --flush-caches

hostnamectl set-hostname jitsi.example.org
cat /etc/hosts

3.jvb密码不一致导致,要保证这三个密码一致

grep JVB_SECRET /etc/jitsi/videobridge/config 
grep ‘user.shard.PASSWORD’ /etc/jitsi/videobridge/sip-communicator.properties  
grep password /var/lib/prosody/auth%2evideoconf%2dtest%2emydomain%2eorg/accounts/jvb.dat

如果不一致可以参考我这篇文章进行修改jvb的密码

4. 确保XMPP里jvb属于管理员用户

Component “internal.auth.videoconf-test.meet.org” “muc”
storage = “memory”
modules_enabled = { “ping”; }
admins = { “[email protected]”, “[email protected]” }

5.有可能你没有jvb这个用户，你可以手动创建

prosodyctl register jvb auth.meet.test.com i2AhIKMh

所有更改都需要重启相关服务
