exception of type 'System.ServiceModel.Security.SecurityAccessDeniedException' occurred in mscorlib.dll but was not handled in user code

Question

I am getting the "Access Denied" Exception while accessing a third party service.

Below is the binding that i am using (Have changed some name to XXXX,YYYY and OOOO as i don't want to show them)

<system.serviceModel>
<bindings>
  <customBinding>
    <binding name="XXXXSyncBinding">
      <security defaultAlgorithmSuite="Default" authenticationMode="UserNameOverTransport"
        requireDerivedKeys="true" securityHeaderLayout="Lax" includeTimestamp="false">
        <localClientSettings detectReplays="false" />
        <localServiceSettings detectReplays="false" />
      </security>
      <textMessageEncoding messageVersion="Soap11" />
      <httpsTransport />
    </binding>
  </customBinding>
</bindings>
<client>
  <endpoint address="https://OOOO--tls.YYYY.com/cgi-bin/OOOO.cfg/services/soap"
    binding="customBinding" bindingConfiguration="XXXXSyncBinding"
    contract="XXXXService.XXXXSyncPort" name="XXXXSyncPort" />
</client>

the service uses TLS 1.2 and am Passing the credential in header as below

 ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

_client.ClientCredentials.UserName.UserName = "XYXYXXYXY"; _client.ClientCredentials.UserName.Password = "XYXYXXYXY&123";

But the service always throw the exception

An exception of type 'System.ServiceModel.Security.SecurityAccessDeniedException' occurred in mscorlib.dll but was not handled in user code Additional information: Access Denied

Answer 1

It has been solved.The Password of the third party service was expired and i came to know this after raising a support request to that third party service.
