Hi @neuquen7, apologizes I didn’t see your post until now. The plugin does work with SSL, I just checked that I was able to fetch multiple sites over HTTPS.
Here are the curl options that are being set (including to not validate SSL certs that may be invalid or self-signed).
$ch = curl_init(); // set up curl
curl_setopt( $ch, CURLOPT_URL, $url ); // the url to request
curl_setopt( $ch, CURLOPT_TIMEOUT, $timeout ); // set a timeout
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true ); // return to variable
curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, false ); // don't verify host ssl cert
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false ); // don't verify peer ssl cert
if ( ! empty( $userpwd ) )
curl_setopt( $ch, CURLOPT_USERPWD, $userpwd ); // send a user:password
if ( $method == 'POST' )
curl_setopt( $ch, CURLOPT_POST, true ); // optionally POST
if ( ! empty( $content ) )
curl_setopt( $ch, CURLOPT_POSTFIELDS, $content ); // send content of tag
if ( false === ( $response = curl_exec( $ch ) ) ) // fetch remote contents
$error = curl_error( $ch ); // if we get an error, use that
curl_close( $ch ); // close the resource
