Hi Rob, Harold,
The Harvester should be able to harvest over HTTPS like any PHP application, but there may be a few issues that can cause problems:
- depending on how the archive you're trying to harvest has configured their SSL certificate, the Harvester may not be able to verify the SSL connection (eg. in the case of a self-signed certificate)
- you must be certain that your PHP installation that the Harvester is running on has SSL wrappers enabled (you can check this with phpinfo(), typically it's the "openssl" extension; on IIS this requires php_openssl.dll)
I would start with checking that your PHP version is 4.3 or greater, and that you have SSL enabled. If you're still seeing the issue beyond this, then please let me know.
