Description
There can be a number of different reasons for JCDS downloads to fail; this article provides steps to narrow down the cause. Please follow the steps below prior to contacting Jamf Support.
Step 1: Determine the scope of the issue
Get an idea for the number of impacted packages and their similarities.
For example:
Is it only 1 package?
Is it only large packages?
Is it only packages in one specific region?
Is it all the older packages, or all the newer packages?
Step 2: Take action based on the scope of the issue
If it's only one single package: it's best to delete it from Jamf Pro and re-upload it, then try again.
If it's only large packages or packages in a specific region: it's best to review the network requirements here specific to the Jamf Cloud Distribution Service and verify that there isn't anything on the network stack that can sever or interfere with longer running connections. Be aware that downloads are served to clients via CloudFront Edge Server routing.
If it's a group of only newer or older packages, or a different specific group of packages: check to see if they are listed as "Availability Pending" in Jamf Pro under Settings > Computer Management > Packages.
If that's the case, the instance is likely impacted by issues described in Some or all of your packages are missing (showing as Availability Pending).
