wp_remote_post returns an error on SSL connection

Question

I'm using wp_remote_post to post some info to a secure connection like this

$url = 'https://example.com/path/file.json';    

wp_remote_post($url, array(
    'sslverify' => false,
    'timeout'   => 60,
    'body'      => $body,
));

But I get an error:

SSL: CA certificate set, but certificate verification is disabled

I though sslverifyset to false should prevent that?

If I set sslverify => true it works but may cause problems on other servers

Here's the complete wp_error object:

WP_Error Object
(
    [errors:WP_Error:private] => Array
        (
            [http_request_failed] => Array
                (
                    [0] => SSL: CA certificate set, but certificate verification is disabled
                )

        )

    [error_data:WP_Error:private] => Array
        (
        )

)

Maybe it's related but on Apache 2.2 it works while on Apache 2.4 it doesn't

Answer 1

Looks like your Apache 2.2 and 2.4 configurations are different. On 2.4 you probably have SSLVerifyClient set to required which would cause it to act like what you are describing. You'd need to set it to none: http://httpd.apache.org/docs/current/mod/mod_ssl.html#SSLVerifyClient
