I too recently tried to set up OpenVPN on a VPS and it was a huge pain in the @ss, even while following a (very long) tutorial. If I figure out an easier way to do this I'll message you in this thread
OpenVPN is just really complicated, which makes sense because of the context and history. But even me who've done plenty of OpenVPN setups through the years, found Wireguard a lot simpler and easier to both learn and use effectively. So if you haven't tried Wireguard, give it a go, the simplicity is pretty nice.
Note: Wireguard is good because it's simple. It makes point-to-point tunnels, it does that well, and that's all it does. You're on your own for the rest.
