A recent update to the Jamf Authorization Server (JAS) caused an issue that prevents proxy server tokens from being created or renewed in environments that are hosted on-premise with a range of legacy Java versions installed. The impacted functionality in Jamf Pro is the ability to send Notification Center notifications to devices with Self Service installed. This issue will cause a notification in Jamf Pro stating that the Push Proxy server token has expired. This issue is resolved by upgrading to Java 1.8.0_141 or later.
Alternatively, environments may wait to upgrade Java until Jamf Pro 10.14 is released as this version will require an upgrade to Java 11. Note that Jamf Pro 10.13 and earlier cannot run on Java 11. Please wait to upgrade to Java 11 until you’re prepared and able to upgrade to Jamf Pro 10.14.
