problem installing minim server on Synology NAS DS212J)

[beckphotonik]

May I ask what resolution and file format are not playing?

That is an excellent question. The "Can't play" message appears precisely in the field on the Naim app that normally shows those data. Thus, I don't know.

Can I find these data elsewhere?

Not sure how to find out about the resolution without installing audio station but the format should be the file extension that you can see using the file manager. Formats like .wav, .flac, .dff, .dsf, .aiff etc.
Formats like .dff and .dsf need to be packaged to DOPwav using minimstreamer and resolutions greater than 24/192 are not supported over ethernet.
