Signing Certificate Expired

[Sushilthapa]

Most of our devices enrolled in Meraki are showing the last MDM check-in date and time a few months back and I realized it is happening because our *meraki.com signing certificates expired on that day. Is there any way I can resync or renew those certificates remotely as all of those devices are already out in the field?

I am not aware of any way of doing this via the dashboard. What type if devices are they?

iOS devices.

Usually, the *meraki.com certificate doesn't impact the check-in functionality and is only a part of new device enrollment.

To investigate further I suggest ensuring the Apple push topic matches on the iOS devices and dashboard.

Dashboard - org > MDM > Apple push topic
iOS device - Settings > General > Profiles & Device Management > Meraki Systems Manager > Tapping on ‘more details’ > Mobile Device Management > Topic.

If it is not matching you will need to have it match. This may involve reverting the push topic and then renewing it - If this is not an option, it may be required to re-enroll the iOS devices.
