Usually you'd connect via a VPN to reach a VPS, which typically has a public IPv4 address, allowing you to run whatever services you need from it.
They’re using a DDNS service, so it seems you’re behind a NAT. Your ISP gives you a fixed IP for free when you ask for it, but by default you’re in a NAT setup, which is typical for providers.
Some internet service providers don’t provide a public IP address; they assign private IPs within their network. If this applies to you, port forwarding isn’t possible without your ISP granting access by opening a specific port. Verify whether your IP is public or private. It’s likely the issue you’re facing has already been mentioned.
