I was not able to test it (for example borrowing a residential IP in a different country) but I suspect they detect OpenVPN via packets inspection, like this example: "Detecting VPN (and its configuration!) and proxy users on the server side" by @ValdikSS https://medium.com/@ValdikSS/detecting-vpn-and-its-configura...

There is a Docker container on github ( https://github.com/ab77/netflix-proxy ) that uses a proxy and an IPv6 tunnel that allegedly works with DO's VPS, but I haven't tried it myself.

A normally configured proxy and VPN usually end up with a flagged IP, as I've read multiple reports of people trying with DO or Amazon EC2 nodes.

Mullvad in the recent past had trouble find exit servers in the USA, I think it was reported in their blog.
