php - cURL : "Couldn't connect to host" -

i have solved in past, cannot remember how.

so, i'm trying fetch webpage server, using proxy.

here code :

function curlfile($url,$proxy_ip,$proxy_port,$loginpassw) {      $ch = curl_init();     curl_setopt($ch, curlopt_url, $url);     curl_setopt($ch, curlopt_header, 0);     curl_setopt($ch, curlopt_returntransfer, 1);     curl_setopt($ch, curlopt_proxyport, $proxy_port);     curl_setopt($ch, curlopt_proxytype, 'http');     curl_setopt($ch, curlopt_proxy, $proxy_ip);     curl_setopt($ch, curlopt_header, false);     curl_setopt($ch, curlopt_verbose, false);     curl_setopt($ch, curlopt_proxyuserpwd, $loginpassw);     curl_setopt($ch, curlopt_httpproxytunnel, 0);       $data = curl_exec($ch);      if(curl_errno($ch)){              echo 'curl error: ' . curl_error($ch);     }      print_r(curl_getinfo($ch));     print_r(curl_error($ch));      print_r($data);      curl_close($ch);      return $data; } 

all outputs :

curl error: couldn't connect hostarray ( [url] => http://www.drkameleon.com [content_type] => [http_code] => 0 [header_size] => 0 [request_size] => 0 [filetime] => -1 [ssl_verify_result] => 0 [redirect_count] => 0 [total_time] => 0.007872 [namelookup_time] => 0.007537 [connect_time] => 0 [pretransfer_time] => 0 [size_upload] => 0 [size_download] => 0 [speed_download] => 0 [speed_upload] => 0 [download_content_length] => -1 [upload_content_length] => -1 [starttransfer_time] => 0 [redirect_time] => 0 ) couldn't connect host

so, ideas? going wrong?

your webserver unable connect proxy

• local security settings on webserver - didn't os running on
• a routing issue on webserver
• firewall policy on proxy

the proxy requires authentication? (you should have got 4xx response proxy - if you've got cli adccess try running curl comand line).

the proxy got nxdomain on lookup or didn't ip address expecting.
