How to fix cURL error 51: SSL in Guzzle Yii 2?

Question

Yii

I installed Guzzle in Yii 2 to send a request to an external partner site and receive a json response from there. But there was a problem. I write the following code:

$client = new Client();
$res = $client->request('GET', 'https://api.site.com');
echo $res->getStatusCode();

As a result, I get an Exception with the text:

cURL error 51: SSL: no alternative certificate subject name matches target host name 'api.site.com' (see curl.haxx.se/libcurl/c/libcurl-errors.html)

Can you please tell me how to get rid of this error or how to get around it? Unfortunately, the partner does not want to do anything for his part.

Answer 1

It seems to me that cURL swears at an invalid SSL certificate. Install a valid SSL certificate and the error will disappear.
