英文:
Why does PHP curl returns error 6 for one website?
问题
I'm trying to access www.alberta.ca/ with PHP curl but it returns "Curl failed with error #6: Could not resolve host", although the website is online and returns a nice 200.
Here is my code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.alberta.ca/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$content = curl_exec($ch);
I tried all the solutions I could find, for example adding the following options:
curl_setopt($ch, CURLOPT_DNS_USE_GLOBAL_CACHE, false);
curl_setopt($ch, CURLOPT_DNS_CACHE_TIMEOUT, 2);
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);
But nothing works. Strangely, it works from my localhost, but not from my server.

问题出在我们的服务器配置上，而不是我们的代码。
遵循 @CBroe 的建议，我们只是更改了我们的DNS服务器，现在它可以正常工作。

The issue was on our server configuration, not our code.
Following @CBroe suggestion, we simply changed our DNS server and now it works.
