As MAS mentioned, you must use a valid domain or hostname.

By valid I mean, anyone can resolve your domain or hostname using a public DNS lookup.

https://LetsEncrypt.org provides free SSL certs.

2010 is going off of support end of this year.
No security patches and if something breaks ,no support from M$.
You may want to upgrade before you go through the hassle of rekeying your servers ssl.
