Native XML WebService With Authentication Basic and SSL

Question

I'm using SQL Server 2005 and the Native XML WebServices. The integrated authentication via HTTP:80 works fine. But i need the basic authentication which requires SSL. So if i change the web service to ssl i always get a connection reset (101). I tried several ports 80,443,9999 with the same outcome. What is the error?

--EXEC sp_delete_http_namespace_reservation N'https://ATWEZE99103DAT:9999/sql/s047'
EXEC SP_RESERVE_HTTP_NAMESPACE N'https://ATWEZE99103DAT:9999/sql/s047'
go
--drop endpoint S047SSLPOINT;
CREATE ENDPOINT S047SSLPOINT
STATE = Started
AS HTTP
( PATH= '/sql/s047'
, PORTS= (SSL)
, SSL_PORT=9999
, SITE = 'ATWEZE99103DAT'
, AUTHENTICATION= (BASIC)
, COMPRESSION=Enabled
)
FOR SOAP
