Connection from meraki mx84 to azure appears set up but can't connect to vm

[Chrisatl]

hey, 

I went through the process of setting up a connection from the meraki to azure. I see in the meraki that phase one is connected and azure says it's connected as well. However, when I try to connect to the vm, it does not work. It was working for the first 3 days but now wont let me connect. When i look at the event log, it tells me that ipsec SA expired. Any advice on what I need to do?

Any chance you can try rebooting the MX84?

This is frequently caused by a mis-match of the phase 2 encryption domains.
