ICE server failure when a new participant joins

Hi,

I have a collaboration application built on top of the Kurento Media Server.

Whenever a specific participant joins (When the participant count is more than 6), frequent ICE Server connection issues occur (Ice server connection fails). The participant is not able to see screen-share or hear any other participant’s voice/video.

This problem occurs for some specific users only and not for everyone.

Is there anything that can be done about it?

Thank you.
MA.
