Minimwatch doesn't connect to minimserver on qnap

[gotburger]

I have a similar problem and I have found the operation that causes the problem. But it shouldn't?

Set-up:
- MinimServer 2.2 is the QNAP app on a TS-832X; Server ohnet.subnet=192.168.50.0
- QNAP interfaces *before* the "operation" are both on 192.168.50.0/24
- Minimwatch on Windows 10 with ohnet.subnet=192.168.50.0 (host has one interface and is on 192.168.50.0/24

So far everything works fine.

The operation: Move one of the QNAP interfaces to subnet 192.168.20.0/24

Now:
- The MinimServer does NOT show up in Linn Kazoo on the 192.168.50.0/24 subnet
- The MinimServer status page is accessible over BOTH 192.168.20.0/24 and 192.168.50.0/24

It seems like the (server) ohnet.subnet=192.168.50.0 instruction is ignored.
Haven't found out whether 192.168.20.0/24 is served instead. It is not expected to be so since the ohnet.subnet is set properly as far as I can understand. (Still wondering why the network mask is not required input - hard to understand the interface selection procedure.)

Any idea as to why the server becomes unavailable on the ohnet.subnet specified?
