Hi guys. Firewall MX MX67 - version 18.211.3 Firewall Fortigate I'm having trouble solving a disconnection problem on a non-Meraki site-to-site VPN with a Fortigate. The Fortigate is located inside Azure. The phase 1 and phase 2 configurations are correct on both sides. On the Meraki side, I see an event log showing only connections being reestablished. On the Fortigate side, I can see errors in phase 1 "Payload malformed". I'm using IKVE1, the subnets are being advertised on both sides of the peers. The problem started occurring a few days ago. Another observation, I see the tunnel down on the Meraki dash, but on the Fortigate the VPN shows UP. Has anyone else experienced the same difficulty?
