Can't connect to own TF server

[caodin1]

Srcds shows that the server is online and it shows up in the serverlist but I cannot connect to it myself. I'm running Xp and have forwarded my ports and am unsure what is causing this. I recently started experimenting with coding and servers so unfortunately I need some help.

Does anyone have any suggestions as to what i can try or what would cause this? Thanks in advance!
