"user is having connectivity issues" for lib-jitsi app not recovering

Hi,
Application is built using lib-jitsi-meet, we’ve recently found strange issue, sometimes user fails to transmit it’s video feed, other user’s get blank screen (in Jitsi-meet “user is having connectivity issues”), and feed doesn’t recover.

If we test (all participants) it on Jitsi-meet, issue persists but user’s feed gets recovered after sometime, is their anything being handled recovery of feed in Jitsi meet or it’s just Bandwidth issue and once bandwidth gets better user’s feed will be recovered automatically.

This issue comes when there are more than 3 members.

Another thing is I have doubt that our hosted Jitsi server have weak VM (standard 1vCpu GCP vm), is that’s what causing this?

Thanks in advance.
