On the server that’s behind CGNAT, install Cloudflare tunnel. The tunnel will create an out going connection to Cloudflare, with an open socket; when you try to hit your specified subdomain, Cloudflare will receive your request, send it through the tunnel, and thus allow you to connect to your service.
