Internet Access keeps giving me a red x when testing

Hello I just installed Serviio Pro trial yesterday on Windows Server 2012 R2 Essentials I set it up and have no issue accessing from the local host or clients over LAN but when I turn on my phones internet sharing connect a PC to it and try to connect from my mobile network it doesn't work. I have it configured (http://staticipaddress:23424/mediabrowser) I have manually forwarded that port and I have allowed Serviio through my firewall for domain private and public access but still I get the red x upon testing and no access off LAN. I having been using Subsonic now for about 6 months and although it performs great I was looking for something more visually appealing I have XBMC on my HTPC's but that doesn't help me for remote access. I have started a Plex Server on the same computer prior installing Serviio and while it gives me the eye candy I am looking for I don't like the fact that it doesn't run as a service and it is having issues finding all of my media. I like how Serviio looks and so far I am impressed with the playback performance but if I can't get it to work remotely I have no reason to pay for the license. If you could get me up and running properly I will definitely purchase. I look forward to hearing back from you.
