I wanted to use Netflix times the Probemonat and subscribe with direct debit, but I always get this error message although I have checked everything several times and everything is right.
You can't say that here, just ask the Netflix support, they have information about it.
If you speak English, you can still ask English support, I think the German is already gone.
Alright, thank you
The Netflix system is not going to get direct debit from all banks. Especially with the German banking systems problems appear again and again.
Whether they get it someday you do not know. I recommend that you pay the costs for Netflix via PayPal.
