FortiAP 221C stuck in discovery AC and unable to connect to fortigate firewall

[Ashish-pal]

I have replaced the FortiAP 221c from Fortigate 100F to fortigate 80E. I was connected on 100F but when i connect the same AP to 80E it is showing as discovery AC and stuck in connecting mode. I am able to connect reach the device and able to https also but not able to connect to fortigate 80E at new location.

It may be a firmware incompatibility issue, you can check in the Compatibility Matrix the firmware versions of FortiAP and FortiOS.

There is also a note that applies for this AP:

*These FortiAP models and versions do not support strong ciphers. To allow connections, input the following commands in the FortiOS CLI:

For FortiOS 7.0.0:

config system global

set ssl-static-key-ciphers enable

set strong-crypto disable

end

For FortiOS 7.0.1+:

config wireless-controller global

set tunnel-mode compatible

end
