PHP Soap Fault: Could not connect to host - php

Question

There are many question is similar like this. But I didn't got the solution when tried. Find my codes below:
Soap XML:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:pos="http://PostWebService.org/">
<soap:Header>
<pos:Authentication>
<!--Optional:-->
<pos:UserName>xxxxxxx</pos:UserName>
<!--Optional:-->
<pos:Password>yyyyyyyy</pos:Password>
</pos:Authentication>
</soap:Header>
<soap:Body>
.....
</soap:Body>
</soap:Envelope>
PHP Code:
$client = new SoapClient({soapurl},$params);
$auth = new stdClass();
$auth->UserName = 'xxxxxxx';
$auth->Password = 'yyyyyyyy';
$header = new SoapHeader('NAMESPACE','Authentication',$auth,false);
$client->__setSoapHeaders($header);
$result = $client->__soapCall('{soap function}',array()); // when this line executes it throws me the error "Could not connect to the host"
Please note, My Soap URL is in https. I tried lots other solutions from stack overflow but none of them work. I want anyone tell me why i am getting that error and what i did wrong in the request.
Another Code tried but still the same:
$opts = array(
'ssl' => array('ciphers'=>'RC4-SHA', 'verify_peer'=>false, 'verify_peer_name'=>false)
);
// SOAP 1.2 client
$params = array ('encoding' => 'UTF-8', 'verifypeer' => false, 'verifyhost' => false, 'soap_version' => SOAP_1_2, 'keep_alive' => false,'trace' => 1, 'exceptions' => 1, "connection_timeout" => 180, 'stream_context' => stream_context_create($opts) );
$client = new SoapClient({soapurl},$params);
//Remaining as the same above
When I tried with SoapUI it gives me a response.

Answer 1

Finally, I got the solution,
I found the problem. The host I was trying to connect is redirecting to another domain name. For some reason, PHP 5.6 doesn't carry the location automatically. So i defined the same soap url in the location options.
Eg:
$params = array('location' => {soapurl});
$client = new SoapClient({soapurl},$params);
Thanks for your time. :)

This solution worked for me.
E.g.
$client = new SoapClient('https://example.com/webservice.php?wsdl');
$client->__setLocation('https://www.somethirdparty.com');
