I can't really provide you with help specific to Nokia phones, but 
given your description:

Did you enter the Bonjour address into the phone by any chance?

Bonjour addresses will only work on Macs, iPhone, iPod Touch and 
Windows, if you have manually installed Bonjour onto it. I think it's 
unlikely that Nokia phones support it.

Therefore, please try entering the IP addresses, including port 
number. You may also want to turn on password protection for the AJAX 
Remote, as that ensures the first thing the browser will receive is a 
static page. If password protection is turned off, the AJAX web app is 
served to the browser directly, which may - if the browser is not 
capable or up-to-date enough - leave you with nothing but a white 
screen.

You may also want to turn on logging for the AJAX Remote and watch 
your console.log in Console.app for accesses from your phone. That 
way, you can exclude that it is a network problem.
