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.
