Watch Netflix Movies From Abroad?

I just wanted to look at Netflix movies that are not available in Germany. That's why I then used a VPN that I'm in the US and theoretically it worked, but when I looked then came the error message that a proxy or Unblocker is used and I have to turn this off. I then switched off the VPN without closing Netflix and then came to look at the error message that I'm not the DE region.

Has anyone with experience, or knows if you can avoid these error messages.

Netflix has already installed their useful security systems, which are not easy to circumvent.

There you have no chance. Netflix is well behind blocking such illegal attempts. They always close such gaps quickly.
