Hi suddely I start to get this error curl_error: Peer certificate cannot be authenticated with known CA certificates on paypal transactions on my site. The certificate name is VeriSignClass3PublicPrimaryCertificationAuthority-G5.crt and seem to be valid and seem to be an Intermediate Certificate. The code is the following but it workd for years.
curl_setopt($conn, CURLOPT_HEADER, 0);
curl_setopt($conn, CURLOPT_NOBODY, 0);
curl_setopt($conn, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($conn, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($conn, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($conn, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($conn, CURLOPT_CAINFO, getcwd() . "/CAcerts/VeriSignClass3PublicPrimaryCertificationAuthority-G5.crt");
curl_setopt($conn, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($conn, CURLOPT_PROXYTYPE, "CURLPROXY_HTTP");
curl_setopt($conn, CURLOPT_PROXYAUTH, "CURLAUTH_BASIC");
curl_setopt($conn, CURLOPT_POST, 1);
curl_setopt($conn, CURLOPT_POSTFIELDS, $postString);
curl_setopt($ch, CURLOPT_TIMEOUT, 15);
The site is on a simple hosting and there is no ssh. What should I do? Should I insltall a new certificate? If so what certificate and what is the correct procedure?
