Cannot get it working on a QNAP TS-239 Pro+ II+

[simoncn]

I'm very glad to hear it's working now.

MinimServer takes longer to start the first time because it needs to read all your music files. It writes information from the music files to a cache, and this makes it quicker to start MinimServer in the future because it only needs to read files that have changed since the previous startup.

I'll be interested to look at your log and see if there's anything in there that indicates any problems when MinimServer is reading your music files.
