Cannot connect to outside internet?

[nalie]

Hi,

I dont know how to use this. I´ve the Isubsonic app in Iphone 4. At home have I no problem to play music when using WIFI. But when I´m not connected to my own network at home I cant play any musik.

Please find the error message below that I get when I´m trying to acces from 3G or other Wifi.

"Error.
Either the subsonic url is incorrect, the subsonic servier is down, or you may be connected to Wifi but do not have acces to the outside internet.
Error code 2:
Request Timed Out."

Someone who can help me?

Thanks in advance,
