GuzzleHTTP kills php-fpm when trying to POST to SSL secured URL - php

Question

I'm using Guzzle 6.0.2 ( Also tried with 5.3.0 ) in Laravel environment.
For testing purposes I created Controller with index method to test Guzzle POST request to other web server.
My method:
<?php
public function index()
{
$uri = 'https://payment.my-url.com/gw/testing';
// $uri = 'http://pay.my-url.com/gw/testing';
$client = new \GuzzleHttp\Client();
$resource = $client->post($uri, [
'json' => ['foo' => 'bar'],
'headers' => [
'Accept' => '*/*; q=0.5, application/xml',
'Content-Type' => 'application/json; charset=utf-8',
'User-Agent' => 'Client/1.0',
],
]);
$statusCode = $resource->getStatusCode();
}
When I try to access URL with this method, i receive 502 Bad Gateway from my server, but it only occours if I'm trying to send to HTTPS $uri. If I send to HTTP ( non secure ) uri then my request goes to foreign web server and there I can dump POST data array.
I have nginx 1.8.0 and PHP 5.6.9 on OSX environment.
I also tried to add extra configuration to guzzle client but this does not make any difference:
'curl' => [
CURLOPT_SSL_VERIFYHOST => false,
CURLOPT_SSL_VERIFYPEER => false,
],
'verify' => false,
Why my web server gives me 502 bad Gateway when I try to send POST to HTTPS uri with GuzzleHTTP component ?

Problem was because of using Bugsnag error handler on Laravel
If changing Laravel handler.php file to use default laravel handler, then error is thrown, if Busnag error handler is used then nginx dies with 502 error, and no error is reported to Bugsnag or Web logs.
Example of file:
<?php namespace Payrex\Exceptions;
use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
// use Bugsnag\BugsnagLaravel\BugsnagExceptionHandler as ExceptionHandler;
class Handler extends ExceptionHandler
{
// ...
}
