Minimwatch doesn't connect to minimserver on qnap

[leo0815]

as already mentioned, I'm already facing the problem for a couple of weeks. Both machines have been powered off several times since then (the linux machine every night to be exact). Furthermore I've just opened vlc on linux and it connects to minimserver too, so there doesn't seem to be a problem with the connection between both machines,

But in the moment when I wanted to click 'Post Reply' I've seen then now minimwatch could connect too. Is it possible that my vlc test somwhow enabled the connection or is it just coincidence?
