Solution to Error 60 SSL Certificate Problem Verify That the CA Cert is OK

I got this SSL error when I want to use a PHP library to access AWS SES. The complete error said

60 SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

I found that it is related to curl setting in php.ini. It needs to know what certificate you use for curl. Because I haven’t define the certificate yet, so this error came up.

First Solution

  1. Download certificate file from
  2. Open your php.ini and add these line below. Make sure the certificate’s path is correct.
    ; CURL Options    ;
  3. Restart your server

Second Solution

If you can’t access and modify php.ini, you need to add this line before curl_exec()

curl_setopt ($ch, CURLOPT_CAINFO, "YOUR_PATH_TO/cacert.pem");

Don’t forget to download certificate first from

Third Solution

This method is not recommended due to security issues. Just need to add the line before curl_exec()

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

Hope it helps.
