Hello

Please i have a colleague who reported this issue to us today.

They have users in their Kuala Lumpur site who are unable to see any screen shares.

This behavior is isolated to users specifically on that site.

Though Users accessing via VPN are able to see the screen sharing as normal.

The Kuala Lumpur Site has recently had an uplift in bandwidth and the network team have confirmed that there is adequate bandwidth available for the service.

Do you know what might be the cause of this issue.

    Hi,

    when its only related to one site and the users can see the shared screens WITH VPN but not without VPN i would suggest you checking your Firewall rules on that specific branch site.

    Take a look into here. https://learn.microsoft.com/en-us/microsoftteams/qos-in-teams#choose-initial-port-ranges-for-each-media-type
    There is the description which specific ports are needed for that to work even with qos settings.
