cURL error 60 with laravel 5.5

Question

When trying to connect my Laravel app with Facebook app API I get this error

cURL error 60: SSL certificate problem: unable to get local issuer certificate 
(see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

I tried all this solutions :

• I downloaded the file cacert.pem, place it inside my php file and edited the php.ini curl.cainfo = "the path of cacer.pem"
• I edited my file config/session.php 'domain' => localhost

Thank you.

FWIW, When I program with curl in C I typically need to provide a "crt" file, as follows:

curl_easy_setopt(curl, CURLOPT_CAINFO, "ca-bundle.crt");
