FortiAP / FortiGate - Previous authentication no longer valid

[Jeroen]

I have troubles connecting clients to a second SSID. The primary SSID works without any problems.

I tried the following things but i still getting the same error: Previous authentication no longer valid

- Recreate the SSID (Previous this solves the problem)

- Disable WIDS profile

- Reboot Accesspoints

- New PSK

It happens on both Windows and Apple devices.

Accesspoints:

- Type : FP221C

- Software: v5.2-build490

Fortigate:

Type: 90D

Hello,

could you please update your FortiAP to our latest 5.2.2 build 225 and tell us if the problem is still present after upgrade.

Thanks

Hi

I have the exact same behaviour, but with two FAP210B (Controller is also a 90D)

Controller and AP are both on 5.2.2

Do you have any news on this? Otherwise i'll give 5.2.3 a try in the next days.

Regards

Michael

The problem is solved but was not a problem of Fortinet. It seems that a LACP trunk between two switches became unstable becuase of a damaged cable. Replacing the cable solved the problem.
