Hello,

  Meraki Switches & APs showing frequent disconnection from Meraki cloud. This is happening the branch is migrating from legacy setup to Meraki SDWAN. (New WAN Circuit as well) . In legacy network all works fine.

I have enabled all required FW rules in MX. Anyone encountered this before?

If not, the  try update switches and ap to latest stable firmwares

If you call Meraki support within 24 hours after the drop they can check the back end logs on the device and tell you what the cause was.  I learned Meraki devices have a series of checks like DNS lookups and pings to 8.8.8.8 to ensure they can reach the dashboard consistently.
