Ok ... after some more work I have it as follow and working. I created the
certificates mentioned below as well :

upstream ucp_cluster {
server 10.12.64.218:444;
server 10.12.64.219:444;
server 10.12.64.222:444;
}

server {
listen 444 ssl;
server_name docker-poc.domain.com;

ssl on;
ssl_certificate /etc/nginx/ssl/docker-poc.domain.com.crt;
ssl_certificate_key /etc/nginx/ssl/docker-poc.domain.com.key;

ssl_session_timeout 5m;

ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;

ssl_ciphers
"ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256";
ssl_prefer_server_ciphers on;

location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;

proxy_pass https://dtr_cluster/;
proxy_redirect off;
}
}
