Action URL does not work

[danield]

Hi, I tried to test with Action URL, with a T48G. But the phone doesn't send something the website. Firmware Version is 35.80.0.130.
Into Remote Controll - Action URI Server IP i tried "any", "127.0.0.1" and "127.0.0.1:10090". Onto my mac I started a web server which is listening at 127.0.0.1:10090. When i type the address http://127.0.0.1:10090 into my browser, I can see a request into terminal of my mac.

But when I save into Action URL the URL http://127.0.0.1:10090, nothings happens. It looks like the phone doesn't call the URL.

What can I do?

Thanks for help.
