SOAP-ERROR: Parsing WSDL Could not load

I have a problem with a host in goDaddy

I have a php with the following code

soapclient("http://traceme.ddns.net:2021/trazabilidad/ws_trzagrosmart.asmx?WSDL",[ "trace" => 1, "exceptions" => true]);

on my local XAMPP works normally, but on the host it tells me

  

Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing   WSDL: Could not load from   ' link '

I already use the NuSoap library but the problem persists, I also verified that the SOAP client was enabled, and I also handled the 5.5 check on both servers.

also verify that the service I'm trying to call is active.
