Minimwatch can't find Minimserver

[swdick]

I use Minimserver on my Synology NAS, version 2.1.2 and Minimwatch on my W11 laptop, version 2.1.2.
The Minimwatch icon remains grey , the Log file gives an error message:
Retrying monitor subscription for server at 192.168.178.28:9791 (attempt 15)

What is wrong?

This message means MinimWatch is being blocked by your Windows firewall. If your Windows network type is set to Public, you need to change this to Private. If it is already set to Private, there is some issue with your firewall settings.

Yes, setting the network to private did the trick.
Thanks a lot.
