install4j auto update download failure

I'm trying to use the auto-update feature of install4j. The updater is configured as stand-alone and is launched by the user from a menu item with the code snippet from the installer configuration. The updates.xml URL is configured in the Auto-Update Options screen.

The updater is started correctly but then it fails with the error "The update information could not be downloaded from ". The URL is correct and the xml file can be viewed from a web browser on the same client computer. I tried disabling the firewall and antivirus, but nothing has changed. I use install4j version 6.1.6 and the target platform is Windows (tested on Win7 and WinXP just in case).

Can anyone suggest a possible reason for this failure and/or a way to get more diagnostic information?

Thanks in advance

I solved the problem by disabling browser integrity check in the CloudFlare settings. This means that install4j is sending malformed HTTP headers that are interpreted by the CloudFlare firewall as suspicious.

I do hope that this install4j bug will be fixed, since allowing access at the CloudFlare level means that the server is more exposed to actual threats.
