php Curl 405 Not allowed

Final Update It appears that the targeted website blocked DO IPs and are giving the problems which I've been resolving for days. I spinned a EC2 instance and manage to work the code working, together with caching etc so as to reduce the hit on the website and allow my user to share the website.

-

UPDATE: I manage to get the Html by setting curl error to off, however the website other than returning 405 error is also not setting some cookies which are required for the website content to be loaded.

curl_setopt($ch, CURLOPT_FAILONERROR, FALSE);

I'm using the following codes for ajax->PHP to retrieve og: meta for websites. However, there's 1 or 2 specific sites that returns error and would not retrieve the info. With the following errors. The code works seamlessly for majority of the websites.

Warning: DOMDocument::loadHTML(): Empty string supplied as input in /my/home/path/getUrlMeta.php on line 58

From curl_error in my error_log

The requested URL returned error: 405 Not Allowed

And

Failed to connect to www.something.com port 443: Connection refused

I have no problems getting the html of the website when I use curl on my server console and no problem retrieving information needed for majority of the websites using codes below

function file_get_contents_curl($url)
{
    $ch = curl_init();
    $header[0] = "Accept: text/html, text/xml,application/xml,application/xhtml+xml,";

                break;
            } while (0);
            }
        }

    }
}

echo json_encode($rmetas);


die();

UPDATE: Error on my part that website is not https enabled so I still have the 405 not allowed error.

Update: If I do a curl -i from console I get the following response. A error 405 but it follows by all the HTML that I need.
