Member can not connect until kick with all rooms

Hi,

I can not solve a problem with ofmeet.

If he left the room and tries to connect later, he sees only himself, all other black screens, but after restart the Openfire or if all kick and re-enter the room all see each other.

In the log browser and the Openfire nothing.

Why is this happening?

Where can I get detailed information about the work Jitsi VideoBridge?

Put the log file nohup.out

Events:

Both members are able to see only themselves. One member sees black screen instead of other member. Both members are able to see each other after they re-enter conference room.
