I use Libreelec 21.2 with TVheadend 4.3. Everything is currently working. I can record and play, everything is fine. I wanted to delete old channels on TVheadend and add new ones. I can log into the web interface as a normal user. But then I can't change/edit the channel list, for example. I actually created an admin, but I just can't get in. I don't know if it's a mistake on my part, i.e. wrong name/password or a problem with TVheadend.
The next step is to use ssh to access the Libreelec PC and enter "systemctl status tvheadend.service", and get the answer "Unit tvheadend.service could not be found." How can that be? TVheadend is running and making recordings, all channels are there with picture? What also surprised me is that previously the name and password were entered in the TVheadend add-on, but that has disappeared in TVheadend 4.3?
So my main problem is how do I get back to the TVheadend web interface as an admin?
Thanks for any tips
