multiple users are unable to connect to wifi network. Meraki dashboard shows authentication and association failures for the SSID in question. what could be the issue for 802.1x authentication with Radius?

if the tests are successful with the same credential as users are connecting, then we can rule out shared secret mismatch, AD issues. look at radius logs, as suggested by marce1000 below, check if there was any update pushed to clients...
