Forticlient 6.2.6.0951 disconnects MS Teams video

Hello I am having issues recently and some of our users also, where the VPN disconnects when being in a MS Teams video chat. I loose vpn then loose access to the resources etc that it connects me to. I notice that when taking part in a Teams audio only call it does not happen. Switch on video and it will disconnect in a couple minutes. Any ideas, Qos issue perhaps dropping the vpn i know they can be sensitive to packet lose.

Thanks
