we have resolved the issue.
to resume: we needed to fix outgoing proxy settings.
we are using AWS to get faster downloads, so the AWS Ip's/urls needed to be white-listed in our configs.
Thanks for your support

Can you use a fiddler as a proxy?

Then, set the proxy to the extraction context.

 WebProxy proxy = new WebProxy("http://127.0.0.1:8888/", true);
 extractionsContext.Options.Proxy = proxy;
 extractionsContext.Options.UseProxy = true;

I would like to see the HTTP request and response messages when the problem occurred.
