Jitsi-videobridge load balancing

I am using new jitsi installation and jitsi-videobridge2 installed another instance. Two bridges are working correctly but not load balancing.

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.ENABLE_STATISTICS=true org.jitsi.videobridge.STATISTICS_TRANSPORT=muc org.jitsi.videobridge.xmpp.user.shard.HOSTNAME=mydomain.com org.jitsi.videobridge.xmpp.user.shard.DOMAIN=auth.mydomain.com org.jitsi.videobridge.xmpp.user.shard.USERNAME=jvb org.jitsi.videobridge.xmpp.user.shard.PASSWORD=Eu org.jitsi.videobridge.xmpp.user.shard.MUC_JIDS=JvbBrewery@internal.mydomain.com org.jitsi.videobridge.xmpp.user.shard.MUC_NICKNAME=9897c620-0f2a-498c-b174-f73c6fece0e1 org.jitsi.videobridge.xmpp.user.shard.DISABLE_CERTIFICATE_VERIFICATION=true org.jitsi.videobridge.STATISTICS_INTERVAL=5000

is there any misconfiguration ?
