API causes "Curl error: OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054"

Question

This is not related to homestead nor vagrant nor laravel.

I have an app service running on PHP 7.3 on a Windows Azure server.

Here's the code I'm running in relation to my cURL call:

$resCurl = curl_init();

$url_API = 'https://example.com/api/someMethod';

curl_setopt( $resCurl, CURLOPT_HTTPHEADER,  array( 'Content-type: APPLICATION/JSON; CHARSET=UTF-8' ) );
curl_setopt( $resCurl, CURLOPT_POSTFIELDS, $jsonRequest );

curl_setopt( $resCurl, CURLOPT_POST, true );
curl_setopt( $resCurl, CURLOPT_URL, $url_API );
curl_setopt( $resCurl, CURLOPT_RETURNTRANSFER, 1);

$resultAPI = curl_exec( $resCurl );

When this is executed, I keep on generating this error:

Curl error: OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054

Running the command prompt, I can execute php -i to see if openssl has a directory it's reading from as well a file mentioned:

I've already checked the directory and downloaded the most up-to-date cacert.pem file from here: https://curl.haxx.se/docs/sslcerts.html

I DO NOT want to solve this issue through turning off SSL verification by setting my CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER to false.

Any advice?

UPDATE:

I hardcoded options for both CURLOPT_SSLCERT and CURLOPT_SSLCERTTYPE:

curl_setopt( $resCurl, CURLOPT_SSLCERT, 'D:\home\site\cert\cacert.pem');
curl_setopt( $resCurl, CURLOPT_SSLCERTTYPE, 'PEM' );

And the error is different now:

unable to set private key file: 'D:\home\site\cert\cacert.pem' type PEM

I would upload a private key, but there are no private keys for this public cacert.

Error `10054` means "Connection reset by peer" indicating there is some kind of connection issue going on between the client and server. Perhaps interrupted by a firewall or routing issue. — drew010, Nov 11 '19 at 16:15
@Drew010 you wer right it was a firewall issue, post an answer and I'll accept if Jack Jia doesn't get to it first — LatentDenis, Nov 16 '19 at 17:45

Based on my test, everything is OK.

My environment:

Windows 10 1809
PHP 7.3 (7.3.11)
cacert from https://curl.haxx.se/ca/cacert.pem

Code:

    $resCurl = curl_init();

    $url_API = 'https://example.com/api/someMethod';
    $jsonRequest = '{"a":"aaa"}';
    curl_setopt( $resCurl, CURLOPT_HTTPHEADER,  array( 'Content-type: APPLICATION/JSON; CHARSET=UTF-8' ) );
    curl_setopt( $resCurl, CURLOPT_POSTFIELDS, $jsonRequest );

    curl_setopt( $resCurl, CURLOPT_POST, true );
    curl_setopt( $resCurl, CURLOPT_URL, $url_API );
    curl_setopt( $resCurl, CURLOPT_RETURNTRANSFER, 1);

    $resultAPI = curl_exec( $resCurl );
    $print_r($resultAPI)

Result:

Suggestion

So, basically this part of code is fine.

As you said that it is not related to homestead nor vagrant nor laravel. So, it is most likely a network issue. Maybe you can try to restart the Azure server.

Update

Confirmed by @LatentDenis, he finally found that the problem was caused by the firewall, which can give us a clue to narrow down similiar issues.

Thanks for testing on your end, I went ahead and updated my question at the end - do you know anything about the new error being generated? – LatentDenis Nov 12 '19 at 15:21
I realize the issue, the resource I was attempting to access had our IPs blocked. If you revise your answer to say account for blocks on the server (firewall issues) I'll accept! – LatentDenis Nov 16 '19 at 17:44
@LatentDenis Your case would point out a direction to others who have similiar issues. Updated in my answer. Thanks. – Jack Jia Nov 17 '19 at 12:37
