FortiClient v7.xx with Sophos Central issue

Hello community,

we use Sophos Endpoint in the current version in our company. Our macOS users almost all have the same problem:

FortiClient v7 with Sophos installed does not establish a VPN connection.
FortiClient v6.4.6 with Sophos installed establishes a VPN connection successfully.

We can replicate this behavior over and over again. I personally suspect a problem with FortiTray, which is only on board in the new version 7.

I have already set all conclusive exceptions in Sophos, but I do not manage to establish a VPN connection.

Does anyone have the same prpblem and can help me?

Thank you!
