This can happen if you go to a https page without the SSL.
I turned on the SSL, but nothing hapenned. (lNET - SSL - properties)
I examined the traffic with Wireshark. It occured to me that Firefox sended cookies, while synapse didn't. But when I turned off the cookies in FF it worked. So it doesn't depends on cookies (I think).
I tried to extract the sended objects.
Synapse - doesn't work
GET /akt.php HTTP/1.1
FF - works
GET /akt.php HTTP/1.1

And one more thing. When I type the IP number ((
http://123.45.67.8/ instead of the name) in FF, I get the same error.
