Astra19.2 - Sender disappeared

Good morning
with so many HD channels disappeared, search as History HD. So a renewed search did not bring the transmitter back. In addition, a few more channels are affected with me.
Can anyone confirm that or is it somehow up to me ?!

Your question is in the wrong section of the board.
Sky germany has changed transponder settings.
I will transfer your question to right section.
I‘m sure, the collegues will help you!
