Alright! I see. That's sounds quite good. Thanks for your quick answer! Much appreciated. I've already asked for help in that community forum and also in discord chat channel. But no comments or solutions so far :(

[webtome]

I got a tip in Discord: $ find /srv/homeassistant ! -user homeassistant -print But my result was empty. And that should be correct I was told. "That's good, but odd."

So, still I have this error. Anyone?
