Openfire 3.9.3 & jitsi videobridge 1.3.0 can not see 2nd participant

I searched in the forum and found someone already faced this problem.

The major answer is related to IP address and host name.

I’m also facing with this problem, however I could not solve it by changing IP to server name.

I tested on 2 machines one is Windows server 2008 and other is Ubuntu14.0LTS.

I got same result.

The participants’ image are not shown.

The server always show bellowing error when second participant join

Could any one tell me the reason? and how to fix this?

Thanks a lot

I would like to add my voice - a pleas for help

I have OPENFIRE 3.9.1 and 1.3.2 videobridge plugin - no other plugins

server is Windows 2003 running JAVA 1.7.65 (not sure if even needed)

I have turned on anonymous login in registration settings and script syntax in HTTP bind setting

my web url https://myserver:7443/jitsi/apps/ofmeet will not let me see the 2nd participant, nor their audio - just the grey box

I see the sessions in client and the room in group chat thru the OPENFIRE server admin

any help you could give would be much appreciated


It seems that jitsi-videobridge development has been stopped. So no one answer our questions.

You had better to move to another direction.
