I’m trying post the following(obfuscated) XML to the our Fax Finder server to send a fax.

<?xml version="1.0" encoding="UTF-8"?>

<schedule_fax>

<cover_page>

<subject></subject>

<comment>testing</comment>

<url>http://192.168.168.240/ffws/v1/data/cover_pages/mts_template1.pdf</url>

</cover_page>

<recipient>

<fax_number>8885551212</fax_number>

<organization>This Organization</organization>

<name>Scott Recipient</name>

</recipient>

<sender>

<fax_number>8885551212</fax_number>

<name>Sender Name</name>

</sender>

<location>external</location>

<url>http://s3.amazonaws.com/some_buck/......</url>

</attachment>

<schedule_all_at></schedule_all_at>

</schedule_fax>

and I’m getting the following response.

<response>

<message>failed to retrieve attachment: failed to retrieve cover page: 403</message>

</response>

I’ve verified that the the user and pass are authenticating correctly. I’ve also verified that the external URL is, indeed accessible.

Am I missing something here?

UPDATE: I’m working with model FF230 and Version 2.1.0
