Four Way Handshake Timeout

Hi All,

Wondering if anyone else has had this issue or could advise?
There are lots of User 802.1x Authentication Failure's in our event log with the Four Way Handshake Timeout error - Is there any recommendations to try and resolve this?

Thank you!

    we're experiencing the same issue at one of our clients infrastructure. we have an mc3200 with about 70  

    AP822i. the authentication failure issue occurs with different devices (iphones, samsung galaxy, etc.) and different networks. did you manage to find a solution for this? any help is appreciated...

    Hi Guys,
     
     Maybe try running a packet capture on your RADIUS server. Are the request packets coming in? Any logs for rejections on the server?
