Non-Meraki VPN Issue with MX Firmware 19.2.1

[Holli69]

We suppose there is an issue with MX FW 19.2.1 with DH21.

After updating 5 networks with MX 19.2.1, we noticed once or twice a day in all these 5 Networks a connection loss of all iPads (no IP).

We use Certification authentication against an MS NPS Server in our Data Center.

All other Networks with FW 19.1.7.2 with DH14 work fine.

If we downgrade these 5 Networks again to FW 19.1.7.2, everything works fine.

Has anyone else explored this issue?

The Release notes don't mention anything, I think it would be interesting to confirm with Meraki support.

I would revert the firmware uprade and see if the issue is resolved (at least revert it on one site).

@PhilipDAth : Revert to FW 19.1.7.2 resolves the issue. So I assume there is a bug in MX FW 19.2.1
