https (ssl) configuration problem ?

Hi

I've have FDS Working locally fine under Http,
I'm trying to configure a server under https, both Flex-admin and the application work fine under
Http, but under Https Flex-admin/console reports a RPC error - http Status 500,
and the Application reports

[RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Unable to load WSDL. If currently online, please verify the URI and/or format of the WSDL (null)"]
