Specific devices becoming unreachable
I have a weird issue that I think might be related to TCP timeouts but I haven't been able to diagnose.
Recently replaced Fortigate firewalls with WG T45 and T25. Servers are in Azure, BOVPNs are setup and operating properly.
Badge reader control panels are set to static IP and connect to port 3001 over BOVPN to Azure server hosting DB for backend.
Randomly several panels will go offline and can't be pinged from the server or local network.
I can however still ping the devices from the WG diagnostic page. Traffic log shows allow on all packets from server.
A reboot to the panels will reconnect them, but it is temporary.
I am at a loss as to what is happening here. Any advice on where to start would be helpful.
