APNS HTTP/2 failed on macOS 10.14 and 10.15

Hi Dear Apple experts,

I am running into MDM push failure issue when switch to use APNS HTTP/2, after MDM server send a APNS MDM push notification, there is no response from Mac device with OS 10.14 and 10.15 (test with Mac OS 10.14.4 and 10.15.3).

Restarting the mac device can make it work but it is just a one-time workaround. If I have new resources to push, then I need to restart the device again.

Issue disappears if switch to use legacy APNS HTTP.

Issue does not exist on Mac 10.13 (test withMacos 10.13.6) and 11.0 beta5(20A5354i)with APNS HTTP/2.

Could you please help to check if this is an issue of macOS 10.14 and 10.15? If yes, does Apple have plan to fix it for 10.14 and 10.15?

Appreciated if you can take a look at it with priority as we know Apple has plan to deprecate the legacy APNS HTTP at the end of 2020.

Please let me know if you need more information.

Thanks,
Weijin
Can you please collect a sysdiagnose from the device as well as the logs from your MDM server at the time the issue occurs and file a bug through the Feedback Assistant app.
Hi,

Thanks for the response!
We filed an Apple feedback ticket FB7857393, with sysdiagnose log attached along with the reproduce timestamp.
Could you please help to check this feedback ticket? Please let me know if need any further information.

Hi Dear Apple experts,

We updated the HTTP2 related feedback ticket FB7857393 with latest non-working and working device logs.
We can find some obvious difference by comparing the 2 logs, could you please help to take a look into this?

We can see an error " Thermal pressure level above 0 returning NO" in non-wroking device MDM log, and after that the received APNS message was deleted. You can find the detailed logs in the feedback ticket.

Thank you!
Zhaoying
