Since rolling out 2025.1.80, we have had 2 stores out of 320 that have been prompted with a "Windows Firewall Defender has blocked some features of this app".
The firewall should allow all outgoing connections, so it has to be something else. Just curious what that might be? I can exempt the program, it would help me write my RFC if I understood what eowp was trying to do, that would upset Windows firewall.

Hi,

To be exactly sure what's triggering the warning, you can enable Windows firewall logging:

https://learn.microsoft.com/en-us/windows/security/operating-system-security/network-security/windows-firewall/configure-logging?tabs=intune

We are aware of the browser engine does accept incoming connection on remote debugging port, however by default it only accepts incoming connection from localhost unless this property is set to true:

In that case it will trigger a firewall warning. However the default behavior should not.

Thanks!
