MX 17.10.2 has broken Auto VPN

Hello,
Since upgrading to this firmware, it has broken auto vpn for one of my firewalls, the other 23 firewalls appear to be fine however.

We are past the 14 day rollback time (on the 15th day), so not sure what to do really?

I know it is the firmware that has broken it, because when i look at the VPN status, the timings of when it started to fail are immediately after the firmware upgrade completed.

​

Anyone got any tips ? I have raised a Meraki ticket but they are taking a while to respond.

​

Cheers
