Python Suds URLError Name or service not known iss

问题:

Having a strange issue where I can successfully create a suds Client and print it out:

>>> client = Client(the_wsdl_url)
>>> print client

Suds ( https://fedorahosted.org/suds/ )  version: 0.4.1 (beta)  build: R703-20101015

Service ( wsEnrollmentData ) tns="http://*hidden*"
   Prefixes (1)
      ns0 = "*hidden*"
   Ports (1):
      (*hidden*)
         Methods (1):
            handleIncomingEnrollment(xs:string FIRST_NM, xs:string MIDDLE_NM, xs:string COMPANY_LAST_NM, xs:string CONTACT_FIRST_NM, xs:string CONTACT_LAST_NM, xs:string INV_ADDR_TX_1, xs:string INV_ADDR_TX_2, xs:string INV_CITY_TX, xs:string INV_STATE_TX, xs:string INV_POSTAL_CD_TX, xs:string PHONE_NO, xs:string EMAIL_ADDRESS, xs:string QUOTED_PRICE_AMT, xs:string PRICE_TYPE, xs:string CONTRACT_SIGNED_DT, xs:string TERMS_ACCEPTED_FLAG, xs:string CONFIRMATION_NO, xs:string VENDOR_DB_NO, xs:string ENROLLMENT_ACCOUNT_ID, xs:string SERV_ADDR_TX_1, xs:string SERV_ADDR_TX_2, xs:string SERV_CITY_TX, xs:string SERV_STATE_TX, xs:string SERV_POSTAL_CD_TX, xs:string UTILITY_CODE, xs:string LDC_VENDOR_DB_NO, xs:string LDC_ACCT_CUST_NO, xs:string RATE_CODE, )
         Types (2):
            handleIncomingEnrollment
            handleIncomingEnrollmentResponse

But when I go to call the handleIncomingEnrollment method I get a URL Error:

>>> client.service.handleIncomingEnrollment
<suds.client.Method instance at 0x3c29368>
>>> client.service.handleIncomingEnrollment.method.name
handleIncomingEnrollment
>>> client.service.handleIncomingEnrollment()

  File "/usr/lib/python2.7/urllib2.py", line 1160, in do_open
    raise URLError(err)
URLError: <urlopen error [Errno -2] Name or service not known>

Why would I be getting this "Name or service not known" message? (I get the same error even when passing arguments to the method).
