Start with the failure reported at /app/lib/utils.js and reproduce the Let's Encrypt submission using the jc21/nginx-proxy-manager:latest Docker image and the freedns Certbot package. Investigate the reported name-resolution and package-installation failure; done means the stated DDNS flow can create an SSL certificate successfully.
