Android subsonic unable to connect to server

My server is up and running and working great through a standard browser.
But when I try to connect to it though my phone, I get a "Connection failure. Didn't understand the reply. Please check the server address."
The address is fine, http://XXXXX.subsonic.org/wap
When I test that in my browser, I get a wml file, which looks fine.
I'm using a Samsung Fascinate phone if that's relevant, currently on Android 2.1.
