The cURL error 35 can appear in the Really Simple SSL debug log when the CURL function cannot connect to your website using SSL. Curl often uses a different set of certificates, shipped with PHP. There are several things that can cause this problem, in most cases updating both cURL and PHP to a newer version will resolve this issue. If this doesn’t resolve the problem, please contact your webhosting company, as they can check why CURL is having issues.
