[karma mechanic]

I've seen that error screen relating to the DNS settings. When connected to the SH3 directly is it using different DNS settings compared to the 'normal' connection via WiFi? That might be down to the view of the Internet that Windows sees.

I wonder if the message is because the Netflix server thinks you are trying to overcome a geo-blocking rule. Did you ever do this in the past via a smart DNS service?

One other thing to consider is to delete any Netflix cookies and flush the browser cache. Try different browsers.
