Laravel - Guzzle：获取GuzzleHttp \ Exception \ ConnectException：cURL错误6无法随机解析主机

Question

This is probably the weirdest situation that I ever seen. Basically I have a system built in Laravel 5.1 which needs to make a request to an external system. The thing is, sometimes it works but sometimes I get

GuzzleHttp\Exception\ConnectException: cURL error 6: Could not resolve host: hosthere

Absolutely nothing changes, in terms of code. I run the application with exactly the same parameters and sometimes I get the error, sometimes I get the right response.

Any ideas?

Thanks in advance

EDIT 2 When I execute nslookup domainthatineedtouse.com I get

;; Got SERVFAIL reply from 8.8.8.8, trying next server
Server: 8.8.4.4
Address:    8.8.4.4#53

Non-authoritative answer:
Name:   domainthatineedtouse.com
Address: therealipaddressishere

Can this be related to the issue?

EDIT This is part of the class that is making the connection.

<?php


use GuzzleHttp\ClientInterface;

class MyClass
{
    const ENDPOINT = 'http://example.com/v1/endpoint';

    /**
     * @var \GuzzleHttp\ClientInterface
     */
    protected $client;

    /**
     * @var string The api key used to connect to the service
     */
    protected $apiKey;

    /**
     * Constructor.
     *
     * @param $apiKey
     * @param ClientInterface $client
     */
    public function __construct($apiKey, ClientInterface $client)
    {
        $this->client = $client;
        $this->apiKey = $apiKey;
    }

    /**
     * Here is where I make the request
     *
     * @param $param1
     * @param $param2
     * @return \Psr\Http\Message\ResponseInterface
     */
    public function makeTheRequest($param1, $param2)
    {
        return $this->client->request('get', self::ENDPOINT, [
            'query' => [
                'api_token' => $this->apiKey,
                'parameter_1' => $param1,
                'parameter_2' => $param2,
            ]
        ]);
    }
}

Answer 1

I hope this helps. Basically the problem was related to the server:

In my case, I just needed to reboot and everything seems fine now.
