SUDS question: [Errno 10060] while accessing sharepoint

Hi,
I am facing some problems while accessing sharepoint web-services, while it prints perfectly fine for "Sitedata.asmx", but fails for other services on the same sharepoint server.

Versions: Python 2.7
SUDS: 0.3.9
OS: Windows 7
----------Code---------
try:
import sys
from suds.client import *
from suds.transport.https import WindowsHttpAuthenticated
except ImportError, err:
print err
sys.exit(1)

if __name__ == '__main__':
mntlm = WindowsHttpAuthenticated(**creds) #username = user, password = password)
print mntlm

#-- The Sitedata.asmx works.
#mysite = mysite + '_vti_bin/SiteData.asmx?wsdl'
#print Client(mysite, transport=mntlm)

#-- The Lists.asmx doesn't work
mysite = mysite + '_vti_bin/Lists.asmx?wsdl'
print Client(mysite, transport=mntlm)


----------Error---------
