PROBLEM:
The JeppView for Windows data effectivity window indicates the enroute chart data has expired.
NOTE: If you receive the message "Unable to contact CDA" when opening JeppView for Windows, please review the steps in the following knowledge article BEFORE continuing on:
"Unable to contact CDA" when starting JeppView for Windows
CAUSE:
The CDA Service (Content Delivery Agent) has not downloaded the new enroute data due to a problem with the connection to the server, or the UsingCDA key in the Windows Registry is incorrectly set.
RESEARCH:
-
Open the CDA.log file under C:\ProgramData\Jeppesen\CDA\log and scroll down to the entries for the current date.
NOTE: The ProgramData folder may be hidden, in which case you can type C:\ProgramData in the location/address bar at the top of File Explorer and press the Enter key to open it, or click View > 'Hidden items' in Windows 10, or View > Show > 'Hidden items' in Windows 11.
-
If "Couldn't connect to server" appears in the CDA.log, followed by a url, this url is most likely being blocked by a firewall. The firewall could also be configured to block all communication from the Jeppesen CDA Service.
If a proxy server is being used, the address and port may need to be entered on the Network tab of the CDA Service Monitor in order for the CDA to connect to the Internet. One way to determine if a proxy server is being used is to open Internet Explorer, then go to Internet Options > Connections > LAN Settings. If "Use automatic configuration script" or "Use a proxy server for your LAN" is checked, this indicates a proxy server is being used.
RESOLUTION:
Refer to your firewall vendor's instructions for configuring the firewall to allow access to the Jeppesen CDA Service, as well as the URLs and IP addresses on the following support article:
Server addresses that JeppView for Windows must be allowed to access on the network
If a proxy server is being used, enter the address and port on the Network tab of the CDA Service Monitor.
CAUSE:
The UsingCDA key in the Windows Registry is incorrectly set.
