This is my first time setting up a VPN. Please help me set up OpenVPN connect (OpenVPN Cloud) for FTP access to my home computer from my phone?
At home, windows 10, behind a router, I installed an ISS server, set up FTP, in my home Wi-Fi network, the phone connects to my home computer, FTP works.
I installed OpenVPN connect on my home computer and phone, I tried to set it up for a long time, but so far I can’t configure it to get access to my home computer via FTP from my phone via the Internet.
I'm attaching a screenshot.

At the same time, if OpenVPN connect is connected from the phone, then OpenVPN connect is disabled on the home computer, and vice versa

What instructions should I read? There are so many of them that I'm confused
What do I need to do to make this work?
