cURL error 60: SSL certificate prblm: unable to get local issuer certificate [duplicate]

Answer 1

PCI-DSS 3.1 requires all SSL to only TLS 1.2 so a lot of providers are simply turning everything but TLS 1.2 off. I ran into this type of issue where CURL saw the failure to downgrade handshakes as a failure to verify the SSL certificate. Try finding where your code is doing the CURL call and add this line (be sure to replace $ch with whatever CURL handle your code uses)

curl_setopt($ch, CURLOPT_SSLVERSION, 6);  // Force TLS 1.2

Answer 2

I work with xamps nothing of the above did work for me

I tried this and it worked

1. open vendor\guzzlehttp\guzzle\src\Handler\CurlFactory.php

and change this

$conf[CURLOPT_SSL_VERIFYHOST] = 2;
$conf[CURLOPT_SSL_VERIFYPEER] = true;

to this

$conf[CURLOPT_SSL_VERIFYHOST] = 0;
$conf[CURLOPT_SSL_VERIFYPEER] = FALSE;

it's a temporary solution if you updated this file the changes will lost
