Windows 2012 IIS 8 adding SSL

Here the scenario:
Windows 2012 Server
IIS8

I need to run a web based application off the server. Internally works fine resolving to http://servername. I purchased an ssl cert and would like to set it up on the server. What i'd like to do is create a subdomain off of the hosting company aplus.net  (subdomain.myhost.com)and point that to the local server in house and use the SSL for that. I have an SSL registered and purchased.  I try to add the SSL cert to the server and it disappears from IIS. Do I need to create a domain cert first? Any help greatly appreciated. If I'm completely off on this please advise best steps. Thanks

Guessing you own a domain i.e. example.com and have purchased an ssl certificate with the common name of mysite.example.com .. The way that I would do it is in the dns settings managed by your registrar add mysite.example.com and www.mysite.example.com with an A record that points to your public ip address. At your router forward ports 80 and 443 to the machine local ip address that hosts your website.  In IIS I would create a new site with the bindings for port 80 and port 443 (http/https) with a host header of both mysite.example.com and www.mysite.example.com in the https bindings add your certificate

Whenever I go to add the SSL cert to IIS 8 it shows as loaded and when I go back it's no longer there like it's not accepting it. Even when it's showing there and I do go to add the bindings for 443 the SSL cert does not show as an option to choose. Changes I've made domain.com instead of suddomain.domain.com. The SSL cert is for domain.com. I removed the host header info and the website works internally. Currently the registrar's DNS only has www.domain.com pointing to our internal server. I need to make sure ftp.domain.com still stays where it is. nothing else matters as this is a utility domain name. Do i also need to make a host file or DNS entry so domainname.com resolves to the local system? Should also not use all unassigned for ip address bindings and just choose the ip address? Any thoughts greatly appreciated. Thank you

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

a SSL cert with the only Subject name of domain.com is not good for www.domain.com you need an alternate subject name of www.domain.com or a wildcard cert *.domain.com.  Did you create the cert request using IIS and then complete the certificate request with the file provided by the certificate authority?

You don't need a host header if it is the only website hosted on the system. As for IP ports the default is fine.
