Meraki APs no longer access to ISE

[jimmy10]

Hi,

My Meraki APs no longer can access to ISE, there has been no change in the configs. When I Run the Radius test from Meraki I get this-

And the ISE logs have this-

The username & password are correct. I can ping the Radius server from all the APs fine. What will be the issue?

RADIUS Pre-shared key?

I can confirm that the Radius PSK is exactly the same on both Meraki & ISE, but there is still the issue as above.

The LiveLog message is pretty clear. You included no information about the endpoint configuration or Meraki timers so hard to know.

8/10 APs failed to connect to your ISE RADIUS server and 2/10 APs are unreachable.  I suggest you start with checking routes and pings.

Are you assuming authentication doesn't work only because of the test results?

If for example your ise is configured to authenticate TLS only, test will fail for sure since it's not TLS, most probably it's not even EAP but simple PAP,
