Problem with MinimServer language setting on Synology NAS

[AndreasR]

Recently, I got a Synology DS223j (running DSM 7.2-64570 Update 3) and was happy to find MinimServer as one of the third party packages in the package manager. I installed it, set up the path to my music collection (currently MinimServer 2.2 update 242 is running), and everything worked fine so far.

However, the default language in the UPNP player app of my streaming receiver shows up in English, while my NAS is set up to use the German language. I looked around in the help files a bit and found the note about overriding the default language in the "serverOptions" property. Since this can only be used with a trial or paid license, I used the former one, put "language=de" into the properties box, and now the UI showed up in German in the UPNP player app.

The help files also said that MinimServer would pick up the language of the system where it's installed and set the language accordingly, but apparently, this doesn't work on my Synology NAS. When I had MinimServer installed on my Windows 10 PC with German UI settings, everything showed up in German in the UPNP player app.

Now I was trying to be smart and tried to rename the "ServerBundle_de.defaults" in the /MinimServer/etc folder into "ServerBundle_en.defaults", but that didn't help either to get German UI texts. Do you have any idea what to do about this issue? Or maybe I missed somethings in the settings?
