I have updated OpenSSL to 1.0.2, changed the ssl.conf file in /etc/httpd/conf.d to include the line

SSLProtocol -all TLSv1.2

I have also upgraded the WSDL file.
In my code I have included the following
 

$context2 = array(
'trace' => true,
'exceptions' => true,
'cache_wsdl' => WSDL_CACHE_NONE,
'ssl_method' => SOAP_SSL_METHOD_TLS,
'stream_context' => stream_context_create(array(
'ssl' => array(
            'ciphers' => 'DEFAULT:!TLSv1.0:!SSLv3:+TLSv1.1',
            'crypto_method' =>  STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
        ),
    )),
    'connection_timeout' => 15
);

$connection = new SforcePartnerClient();

//Create the SOAP connection to Salesforce
    try {
    $connection->createConnection($wsdl, $context2);
} catch (Exception $e) {
    drupal_set_message(t('Unable to connect to Salesforce. Check credentials.'), 'error');

The error message I 'm getting is
Fatal error: SoapClient::__setSoapHeaders(): Invalid SOAP header in /soapclient/SforceBaseClient.php on line 326
This was working perfectly since last Friday. I made no changes to code for this problem to happen. I can confirm this is not a username issue because I have tried multiple users and I have reset the security token multiple times

We are attempting to setup the application using the acceptance login details for SalesForce, there is an issue in regards to TLS 1.0
We are using partner WSDL   to call the soap api, but we faced a issue while calling the login function.
Below is the error:
"UNSUPPORTED_CLIENT TLS 1.0 has been disabled in the organization. Please use TLS 1.1 or higher"
