Minimwatch stopped working immediately as scanning was completed

The value 255.255.255.0 is not the correct subnet value. It is a subnet mask, which is not the same thing.

From what you have said about the icon being green before changing to grey and also abut your computer being connected to a VPN, it is very likely that entering the correct subnet value in MinimWatch will fix the problem.

MinimWatch uses ohNet for UPnP communication with MinimServer. ohNet has a limitation that it can only communicate on a single subnet. If more than one subnet is available, ohNet picks a subnet at random. If it happens to pick the local subnet that includes your NAS, you will get the green icon. If it happens to pick the remote subnet for your VPN, you will get the grey icon. By entering a specific subnet in the ohnet.subnet property, you are preventing this random choice and ensuring that MinimWatch picks the correct subnet every time.

What is the local IP address of your NAS? The correct subnet value will be similar to this address but with the last number changed to 0. For example, if the local IP address of your NAS is 192.168.1.77, the correct subnet value to enter in MinimWatch would be 192.168.1.0.

MinimWatch works with both 32-bit and 64-bit Java.
