Check out Algo [0] if you're interested in setting up a personal WireGuard VPN server. It's simple and hassle-free, especially if you are not familiar with server administration and don't want to be bogged down by details.
I have one deployed on Digital Ocean ($5/mo droplet). All you need to do is run the setup script, answer a few yes/no questions (optional features), paste in your API key, and update the firewall setting on Digital Ocean's dashboard.
If anything goes wrong, deploying a new one only takes minutes.
