I am having trouble adding my FortiGate firewalls to a brand new LibreNMS install (26.1.0-dev.2+fa8b459e2). All devices are running the same FW version (7.2.10) but different hardware 201E, 2000E, 301E, 501E etc. After adding the device SNMPv2 the detected OS is EdgeSwitch. The serial number, uptime, location are all pulled and are correct. I am monitoring these firewalls from other SNMP tools ie LogicMonitor without any issues.
Thanks

I believe I have resolved the issue however I cannot understand why. I removed the SNMP Agent details on the firewall and rediscovered the device and now its detected properly.
