Medion Smart TV, Internet does not work, what to do?

Is

I have bought a new Medion Life X15022 and have everything set up so far and the device also connected to the Internet. However, if I want to open the browser or YouTube etc., or want to test the internet connection, the message "Internet access is not possible! Please check your connection and settings.". However, if I press the Netflix button on my remote, it will work smoothly. I have tried everything (internet connection disconnected and reconnected, reset to factory settings, etc.) but it just does not work.

Would be cool if someone knows an answer, thank you in advance in advance.
