GravityZone 6.22.1-1 Release Notes

Release date: 2021.03.29

Resolved issues

Security for Mobile

Apple Push Notification service (APNs) no longer supports the legacy binary protocol after March 31, 2021. All communication with Apple servers via MDM will be handled by the HTTP/2 protocol from this date forward.

This GravityZone update addresses the changes to APNs, and it is mandatory for the Security for Mobile to continue functioning. After the update, you need to configure your network firewall to allow traffic to api.push.apple.com:443, instead of gateway.push.apple.com, through ports 2195 and 2196.

note Note:
The changes in APNs affects only the communication between GravityZone and Apple servers. GravityZone Mobile Client is not affected, and you do not need to update it.
