I have found that some of our HTTPS sites are not able to be mirrored by
httrack. I am running v3.48-20 on Debian jessie. There isn't much info for
debugging messages but based on my searches, I came across an article that
seems to point at not having the right certificate.

 * <https://curl.haxx.se/mail/curlphp-2003-04/0010.html>
 * <https://curl.haxx.se/docs/sslcerts.html>

Here is the command I am running:

    `httrack <https://www.knowmad.com/> -O "/var/www/servers/www.knowmad.com"
"+*.knowmad.com/*" -v`

Here is a snippet of the debug errors:

22:55:18        Debug:  Wait get: <https://www.knowmad.com/robots.txt>

My next step is to download and compile the latest version of HTTrack to see
if it has newer certificates.


Thanks for any suggestions!
