Panasonic TV, Netflix no longer available?

I recently met a small dream and bought me a 4k TV (Panasonic, Model: TX-43FXW754). Unfortunately, I can no longer call Netflix, which worked before, now appears only a black screen… What can it be? Firmware is up to date. I can't reinstall the app, because it is firmly anchored so to speak. Can someone help me there?

What does "before" mean - in the same device?

Maybe your subscription has expired - who knows?

Or the connection to the Internet is missing.

You have to do all kinds of tests yourself, eg. Does Internet access work with other apps?
