Can't connect to RDS

Hi,

I have some issues trying to connect to RDS server.

My RDS is configured on the port 80. In Homesite+ everything is ok, and I can connect without any problem.

In Coldfusion builder I got the message:

Unable to contact the RDS Server.

For input string: "*

I'm behind a proxy, do you know if I have to set other connection parameters?

Thank you,

Milo
