MacBook Air 2020 with 10.15.7 suddenly loses internet connection

Set up a new computer today and installed the latest F-Secure CP & RDR software (17.8). Was about to install Adobe Creative Cloud and the internet connection died (network settings reported everything was alright). Every other device on the network was working, so it was somthing with this device. I restarted the Macbook and the internet connection was back. Continued the Adobe CC install and again the connection died. I started to suspect F-Secure, ran the uninstaller and now the Macbook could resolve hosts again. I'm pretty sure I gave all the needed permissons for all F-Secure components.

I guess it's something to do with the network filtering? How do I troubleshoot this?

    Just got the same problem with my main Macbook Pro 2014 with 10.15.7. Uninstalled F-Secure and the internet was back. This is a bad trend...

    @wm_mattias do you have any MDM profile installed, especially with System Extension preferences?

    Please, contact customer support, refer to this topic and provide:

    1. fsdiag
    2. screenshot of Network prefpane
    3. output of "sudo profiles show" from Terminal.app

    We've just released a new version of Computer Protection with Network System Extension support and investigating reports of incompatibilities with MDM solutions.

    @kukushechkin On the Macbook Air there were Jamf profiles installed, but on the Macbook Pro no profiles are installed. I'm installing the software on the Macbook Pro again, I'll contact support with the information above if I can reproduce the problem.
