Please note we used DO’s LEMP on Ubuntu 14.04 Snapshot and then followed:
https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-14-04

Then we Installed an instance of WordPress MU by following:
https://www.digitalocean.com/community/tutorials/how-to-install-wordpress-with-nginx-on-ubuntu-14-04

Later we initiated SSL Certificate by following:
https://www.digitalocean.com/community/tutorials/how-to-create-a-ssl-certificate-on-nginx-for-ubuntu-14-04

ALSO WE HAVE PURCHASED A WildCard SSL Certificate from an external CA:
But we are unable to initiate the https:// version of the site??!!

My main concerns are, as per the tutorial:
HAVE CHANGED THE SSH PORT TO A NON CONVENTIONAL PORT + REMOVED ROOT ACCESS

So does the port or user make any difference for SSL Implementation??
