Tvheadend

Hello,

I bought a Digibit R1 to replace my old Wetek Play box. The plan was to install minisatip on Digibit and connect to a Tvheadend running on a RPi with latest Libreelec and TVH addon.
The minsatip and TVH configuration seemed straightforward in advance, however, I have been struggling with bringing up this setup with almost zero success. Now, I would like to make it work with a minimal setup: a single LNB input on port 1 of Digibit.

What I managed to achieve.
- Satip server is recognized by TVH addon
- once the TVH addon ((HTS Tvheadend 4.2.8-36 ~ LibreELEC Tvh-addon v11.0.0.0) on RPi was able to scan the satellite but not able to open any stream
- once TVH addon (HTS Tvheadend 4.3-1774 ~ LibreELEC Tvh-addon v9.0.444) running on WetekPlay was able to open streams and watch tv.
Then without any configuration changes it is not working anymore

I continously get satip: SAT>IP DVB-S Tuner #1 (192.168.10.44@UDP) - no data received, restarting RTSP errors
The satip webgui says No tuner found/active after a while. Come back temporary after a restart. I guess TVH screws up the satip server somehow.

Can you please guide how to make it work, where to start?
