Load balancing - Independent Videobridge test

Hello all,

I am using 2 more video bridges for load balancing. Jicofo is discovering the bridges as I see:
org.jitsi.jicofo.xmpp.BaseBrewery.log() Added brewery instance ...
org.jitsi.jicofo.bridge.BridgeSelector.log() Added new videobridge: ...

But, I get an error on independent testing -
Second videobridge logs -
org.jivesoftware.smack.AbstractXMPPConnection.callConnectionClosedOnErrorListener: Connection XMPPTCPConnection[jvb@auth<domain_name>/IVmrruVg] (0) closed with error org.jxmpp.stringprep.XmppStringprepException: XmppStringprepException caused by '<meeting_name>': org.jxmpp.stringprep.XmppStringprepException: Argument can't be the empty string

Jicofo logs -
org.jitsi.jicofo.AbstractChannelAllocator.log() jvbbrewery@internal.auth.<domain_name>/Second_videobridge - failed to allocate channels, will consider the bridge faulty: Timed out waiting for a response.

Also, I have configured all my bridges to communicate using rest as well as xmpp -
Also, @damencho, Can this be an issue related to not upgrading Jicofo similar to -

Any help would be much appreciated

I solved the issue by upgrading the jicofo and all other components on the main server(JMS). Thanks, @damencho and the whole Jitsi team.
