Unavoidable load remote phonebook error

[satestebang]

Hello!,
I've made a test phonebook.xml file, and stored it at www/html folder at my elastix 2.4.0 pbx, and I can see it from http://192.168.0.100/phonebook.xml on every browser.

Test file includes this only contact:

<?xml version="1.0"? encoding="UTF-8">
<TestIPPhoneDirectory clearlight="true">
<Title>Test</Title>
<DirectoryEntry>
<Name>BUSINESS TEST BROS</Name>
<Telephone>123456789</Telephone>
</DirectoryEntry>
</TestIPPhoneDirectory>

I've registered it on my Yealink T38G, on remote contacts page, but when I open it from display, always get load remote phonebook error.
Firmware is latest, and I've checked xml format, URL, ... What in the world am I doing wrong?
