Microsoft SSTP VPN returning HTTP 503

sstpvpnwindows-server-2008

So I have finally set up my certificates correctly and such, so I'm trying to connect to my VPN. The Windows client is giving me an error with the code "0x800704D4". I looked into it and was told to visit a URL, which I did, replacing the FQDN with my own. I'm getting a page saying that there is an 503 Service Unavailable error.

Any idea how I can fix this so I can finally get my VPN set up?
