Tvheadend

Dear all,
there's one specific channel I can't watch, no clue why... and it's why I'd need your input.
It's "Focus", an italian channel on MUX "Mediaset 2", 36 UHF, frequency 594 Mhz.

I can't see it neither with the raspi pi hat nor with Sundtek MediaTV Pro III. I can watch all other channels successfully.

Do you have any idea what I can look into?

This is what I see on the log:
