authentication timeout (as shown in the following figure). In the
detailed log information, after controller sends the last challenge
packet, Controller does not receive any response.
![]() ![]() Step 2 :Capture packet on the Agile
Controller. It is same with web logs that the controller sends the last
packet and never receives the response. In the packet,
we can see that the current radius
certificate is valid until 18-07-02, the customer's certification
business was normal yesterday, and the authentication failure at today.
![]() Step 3:Test verification: Change the
system time of the terminal PC to 07-01, and the authentication returns
to normal. It is more accurate that the authentication timeout is
caused by the expiration of the radius certificate.
Step 4:After re-imported the RADIUS certificate to Agile Controller server, the service is restored.
