Joomdle web services

Hello,
running Joomdle: System Check, with both Moodle to Joomla and Joomla to Moodle HTTP Connectivity correctly working, I find the following error for Joomdle web services:

An unexpected error happened: 630: Unable to read request

Didn't find any info about this error.
Anyone knowing what is it and how to fix it?

Thanks in advance.


VERSIONS
JOOMLA 3.2
MOODLE 2.6
JOOMDLE 0.95

I don't remember seeing that error before. Try enabling debugging in moodle tro get more info about it.

Thanks Antonio for your quick answer.
I tried setting DEBUG MESSAGES to ALL level in MOODLE but I don't know where I should see the infos on my error, that appears on the JOOMDLE panel in JOOMLA. There is one thing interesting though and it is that, if I set DEBUG MESSAGES to DEVELOPER, it says that the MOODLE to JOOMLA Connectivity doesn't work too ("Moodle cannot connect to Joomla" is the message), still with the "630:Unable to read request" message for the Joomdle web services.

I thought more info would appear along the 630 message.

It seems that error is shown when input for the xmlrpc request cannot be read.

Thank you, even so late, Antonio. After a long time when I had to set the Moodle part of my site, I'm back and still with the same problem. In the meantime I tried to change many things in my environment. Have you (or anyone else, I'm really in a mess) any idea of why, after having followed every instruction that I've found, it still can't read the xmlrpc request (or whatever could cause this problem)?

I don't know what the problem might be, as I have never seen that error before.

Looking at moodle code, it seems it cannot read the xml request. Maybe something is making it not to reach destination, like firewall or other security measures.
