I have one plugin which you install on wp site and then need to connect it with my production site. For this connection I use CURL request.
I have problem with one wordpress site installed on wpengine. It worked fine for a long time and then suddenly CURL is unable to connect with my production site from this wp site on wpengine.
In curl_error($ch) I am getting "Couldn't connect to host", and I have this problem only with this one site which is one wpengine.
This is my CURL code for connection
$vars = json_encode (
array(
//some params
)
);
$headers = array(
'Accept: application/json',
'Content-Type: application/json',
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://myproduction.com/');
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
$result = curl_exec($ch);
return json_decode($result);
This prolem was happening some time and then suddenly It start to work fine with myproduction site again and all works fine, but now I cannot to connect it with my copy of production site which is on another server ('https://myproductioncopy.com/'). The same error is for copy of production and it's only problem with this site on wp engine.
Have anyone idea what could be a reason of this, or how to find issue or to fix, anything, because I am without any idea.

I have been working on a project to create Azure DevOps work items from a form on a WordPress page. Everything works on my local WordPress installation running on WAMPserver but as soon as it is moved to the development or production servers I get the following error "TF400813: Resource not available for anonymous access. Client authentication required." I am fairly certain that this will be something that needs to be handled on the server but I am not sure what. I was able to due full authentication with the service account that was created for this purpose on my WAMPserver installation but the Windows Server IIS installation is not cooperating. The WordPress page handles authenication and passing data with CURL via PHP. Here is the code.
$url = 'https://organiztion-url/UMCom_DefaultCollection/area_path/_apis/wit/workitems/$'.$_POST['IssueType'].'?api-version=5.0';
$headers = array('Content-Type: application/json-patch+json');
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_USERPWD, 'account:password');
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'PATCH');//PATCH
curl_setopt($curl, CURLOPT_POSTFIELDS, $jsonData);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($curl);
$resultStatus = curl_getinfo($curl);
The solution was to use both a PAT and standard authentication as our local environments could not use the PAT correctly and our Dev, Stage, and Prod environments require the PAT.
Needing information about the goDaddy server error, I used CURL with the following commands in PHP.
I already tested it on another hosting server and it returned me successfully.
I'm using an API for sending messages in whatsapp, everything works: locally and on another server, except on goDaddy.
$endpoint = "https://site...";
$curl = curl_init($endpoint);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER , true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $dados);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);
$executa_api= curl_exec($curl);
curl_close($curl);
$retorno= json_decode($executa_api);
do I need to authenticate something to use third-party API in godaddy?
My phpinfo():
I'm running a curl request from a php script, very straight forward
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://url-here');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postvars);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
This works fine over http but as soon as i use https code execution doesn't pass the curl_exec command and i can't see what the error is. The client side i just receive a 'Connection Reset'.
It's worth noting it does the same thing if i use https://google.com.
Also worth noting that running this from the command like works fine so seems to be an issue running from a php script.
I've added the usual CURLOPT_SSL_VERIFYPEER to false and still no joy.
The same code does however work from my local machine so seems to be isolated to the server.
It's an amazon ec2 instance if that makes any difference.
Welcome any ideas.
Many thanks
Figured this out, curl wasn't compiled with SSL. Did this and all began to work.
This has been driving me crazy for 2 days - I have 2 PHP functions as detailed below both using curl. They point at exactly the same 'XML gateway' the only difference is one is trying to do it over SSL and the other over unencrypted HTTP.
The HTTP connector operator works exactly as expected, posting the XML file and returning the server response.
The SSL connector returns the ever so vague 'An internal server error occurred. Please try again later'. Nothing shows up in my lighttpd error log, has anyone got any bright ideas?
I'm wondering if it's my web server config/openSSL config. They are both Debian Wheezy standard packages. I appreciate SSL_VERIFYPEER & HOST being set to sale is insecure, however I've been trying to exhaust the options.
openssl s_client -connect xmlgw.companieshouse.gov.uk:443 -ssl3
and the command line function
curl https://xmlgw.companieshouse.gov.uk/v1-0/xmlgw/Gateway
also works as expected on the web server.
PHP functions:
//SSL post function
public function getSSLCurlResponse($xml) {
$url = "https://xmlgw.companieshouse.gov.uk/v1-0/xmlgw/Gateway";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSLVERSION,3);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
//HTTP non SSL function
public function getCurlResponse($xml) {
$url = "http://xmlgw.companieshouse.gov.uk/v1-0/xmlgw/Gateway";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
any help would be really appreciated!
Thanks
I have concluded this was an error in the overall connection to the server - though i could not find any way of proving that. I have managed to find an alternative solution without using an SSL socket.
cURL + proxy noob here, having a hard time. I'm having trouble trying to retrieve a web page from a remote secure server via a proxy. Everything has apparently been set up correctly by a remote dev, such that the following command line instruction works and returns what we're looking for:
curl -k --socks5-hostname localhost:xxxx https://hostname/
However, the following PHP does not echo the requested webpage. Instead it echoes the error 'Couldn't resolve host name':
$proxy = 'localhost:xxxx';
$url = 'https://hostname/';
//$proxyauth = 'user:password';
$ch = curl_init();
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
//curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_URL, $url);
$curl_scraped_page = curl_exec($ch);
$error = curl_error($ch);
curl_close($ch);
if ($error)
echo $error;
elseif ($curl_scraped_page)
echo $curl_scraped_page;
If the $url is changed to a public page, such as Google, the request is successful and everyone is happy.
The connection requires an SSH tunnel if that changes anything at all. The tunnel is open and functioning, as proven by the command line request succeeding.
Is there something obvious that is being missed here?
You need to set option CURLOPT_PROXYTYPE to CURLPROXY_SOCKS5_HOSTNAME, which sadly wasn't defined in old PHP versions, circa pre-5.6; if you have earlier in but you can explicitly use its value, which is equal to 7:
curl_setopt($ch, CURLOPT_PROXYTYPE, 7);
In the option CURLOPT_PROXYTYPE you need to set CURLPROXY_SOCKS5_HOSTNAME option instead of CURLPROXY_SOCKS5.
In this case, the DNS query (for hostname resolving) will be sent to SOCKS proxy and not resolved in the local network.
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5_HOSTNAME);
This constant available since PHP 5.5.23 and PHP 5.6.7 and cURL 7.18.0, so you can simply use it.
