Received unexpected DISCOVERY REQ, session tear down

My Forticloud managed 223C FortiAPs keep failing with this message, "Received unexpected DISCOVERY REQ, session tear down". Sometimes all of them in sequence, which is rather inconvenient. I have been removing things from the network to eliminate possible causes, but there is not much plugged in now. I was originally thinking it might be a chromecast. Fortinet Support has so far been unable to resolve the cause.

Has anyone seen this before? Should an unexpected discovery request to cause the AP to fail? What might the cause be?

    I'm seeing the same thing on mine.
    Did you ever find out a solution?

    No. I removed all of the old Chromecast devices from the network and only drops once per day, usually at 1AM. 
    I was thinking it was related to this:

    It started happening again. I upgraded firmware to 6.0, but it didn't help.
