I have been in contact with godaddy support and they told me it makes no difference for paid or free hosting in regards to the CURL setting.
Also here is the CURL info they gave me that should work:
"How would a user use CURL to connect via HTTPS?
Go Daddy's HTTPs Proxy requires special options to be placed within any CURL session before it can be used with the HTTPS protocol. The following options will need to be entered into the CURL Session...
curl_setopt ($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt ($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
curl_setopt ($ch, CURLOPT_PROXY, 'http://64.202.165.131:3128');
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
Current Proxy IP's as of 2/14/07
64.202.165.131
64.202.165.132
64.202.165.133
64.202.165.201"
However, I can not get it to work with any of these ips, but perhaps others will with a different host. I am really thinking the only thing it could be is a godaddy communication problem with the paypal express.
