Description:
------------
I have an error "Error Fetching HTTP header..." when trying to use webservices from Interpro (WSInterproScan). My script run well before.

Reproduce code:
---------------
# URL for the service WSDL
   $wsdlUrl= 'http://www.ebi.ac.uk/Tools/webservices/wsdl/WSInterProScan.wsdl';
# Get the object from the WSDL
   $proxy = new SoapClient($wsdlUrl, array("user_agent"=>"eudbase"));

   $params = array();
   $params['email'] = 'kk86bioinfo@gmail.com';
   $params['seqtype'] = 'P';
   
   $data = array();
   $data[0]['type'] = 'sequence';
   $data[0]['content'] = ">cn1\nMWCAMGQVFEELSKESEAIRCYERARDCDEDEDSIALAKLAEGYEKMAREAAKDGRQ";
   
   $jobId = $proxy->runInterProScan($params, $data);
   echo "$jobId\n";

Expected result:
----------------
I should received the job submission ID for the service.

Actual result:
--------------
