Reproduce the SSL Certificates flow with Nginx Proxy Manager 2.10.4 and the jc21/nginx-proxy-manager:latest Docker image. Start with the logged certbot command and its package-installation failure, then verify the DNS and network conditions involved; done means the Cloudflare DNS challenge issues a certificate successfully.
