Took me a while to finally get it working but I imported my SSL certificate from linux across to Windows Server 2012.
Had to create pfx file so that IIS would import the SSL certificate rather than having to request a new one again.
Finally found the answer here on how to do the creation of the pfx so i could import it easily
