Thanks a bunch, that was also my assumption but I am a bit lost at the documentation given by photoprism in that regard (see OP). Some variables I can guess what they are, but for example they ask for the path of the certificates and they are in the docker container… not sure where that is.

I am a complete noobie with those things, so I learn slowly :P

I can access it, the app does work, but within the app it says I am offline and some backend stuff (I guess hosted by photoprism itself) isn’t working.
