This might answer your question. It's straight from the help guide in CCA. "When all else fails, read the instructions" :-)
Connection Options
This window appears when you click Connection Options in the Create New Customer Site window or the Modify Customer Site window.
- When you create a customer site and discover devices using a starting IP address, subnet, or range of IP addresses, CCA first uses HTTPS protocol to connect. If connection via HTTPS fails, CCA retries the connection using HTTP.
- When you use the Hostname/IP Address option to connect to a single device, CCA connects to the device using the protocol selected in the Advanced Options tab. The default is HTTPS.
- On subsequent connections to a customer site or standalone device, CCA uses the same protocol that was used during device discovery.
You can modify the HTTP Port field only if you are creating a customer site. The field must contain the number of the HTTP port that CCA will use to communicate with devices in the community.
If you enter an HTTP port number other than 80, the default, add and configure the port before you add any devices to the site. To change the port number afterward, use the HTTP Port window.
The port number used for HTTPS connections cannot be changed; it must be 443.
You can select an access mode and a privilege level only if you are creating a customer site. Your selection is used when discovering devices and connecting to the site for the first time.
Click OK when you are finished with this window.
