safari 2 cant connect to Web UI

hello,
after upgrading to tiger, I cannot connect to Zoë's web UI anymore
using Safari 2.0

I get an "Unauthorized" error message

using another browser like e.g. Camino works fine

I changed the port number and restarted Zoe, and tried to connect to
the new port number, but the problem persists

anybody has seen this problem? what could be the solution?
thanks

this is the debug log when trying to connect with safari 2.0
