Forti AP No LLDP neighbors found

Good morning everyone,

I'm experiencing an issue managing my FortiAPs through my FortiGate. Specifically, I have 8 FortiAPs that I plan to manage centrally; however, as highlighted in the attached image, only 6 devices are currently online and accessible.

Network Configuration

Headquarters:

• FortiGate 91G

• IPSec VPN connections established to the retail locations

Retail Location:

• Mikrotik Router

• FortiSwitch

• One or more FortiAPs

This is the only retail location showing this kind of problem. Has anyone encountered a similar situation or have any suggestions for resolving the issue? Any guidance regarding configurations, firmware updates, or specific settings to ensure that all FortiAPs are properly recognized would be greatly appreciated.

Thank you in advance for your support and valuable insights.

Best regards,
Corniola AlessandroManaged FortiAP
