How does an ISP determine traffic in an encrypted channel?

Question

openvpn

I received a warning from Digital Ocean that there is traffic from my virtual machine downloading media content that is protected by copyright.

On a virtual machine there is only OpenVPN

How, the provider receives information on a traffic in my ciphered tunnel?

Answer 1

The scheme is as follows:
Desktop -> (Provider) -> OVPN Encrypted Tunnel -> Digital Ocean -> Media content. Those. Digital Ocean sees where you go and what you download, the provider and the tunnel have nothing to do with it
