So far....

I have a running TVheadend on a Bullseye installation on a SDcard for my Raspberry Pi 4. For a while I'm trying to install TVheadend under Bookworm. My first problem was that the second German TV channel (actually the entire family incl ZDFneo, ZDFinfo and 3sat) won't shop up. The rest of the channels were doing alright. With my last attempt I have an even bigger issue: after login in I get a 403 forbidden error, i.e. I don't get any chance configuring TV headend nor any access. I tried with different browsers (Firefox, Chrome, Konquerer), all security options of the browsers switched off with no improvements.
