Video Freezing for Some Participants

Hi,
I’m using JITSI Lib to implement my conferencing system. Everything is working perfectly fine but many time few participants complain that they are not able to see my video and its getting stuck where as other participant keep seeing perfectly fine. But this complain is very often from different participants and then finally they need to refresh the page to come back to the conference and again they can see me correctly. Though there is no error log message visible.

Kindly suggest what could be the error and how to overcome/worked around for this problem.

Regards

As usual no reply…disappointed…
