4 FortiAPs this morning offline - what can we do?

[RolandBaumgaertner72]

Hi,

we have FGT90G with 7.4.7 and 4 FortiAPs with 7.4.X  - everything working without any problems for almost one year. We didnt change anything and this morning all FortiAPs show offline in Managed Forti APs.

No changes were made in interface and everything is still enabled. Since they have fixed IP we can access and ping them without problems.

So with ping there should not be any interface/ switch / power issue but we tried connecting one AP directly on the interface on the FG and the same result. We tried with this AP also de and authorize and still offline.

We restarted wireless controller demon and still no difference.

Any suggestions?

Thanks
