Error 5400 and 22056 Cisco ISE

Hey everyone,

Just wondering if anyone knows why a user would get a Event 5400 Authentication failed (Failure Reason is 22056 Subnet not found in the applicable identity store(s).  The laptop has just gone through a successful authentication and switched to a docking station (to test how a normal user would do) and we're testing this new configuration now. 

In the live logs, we can see it switched from 802.1x to MAB and not sure why if it just worked with 802.1x about several minutes ago.

See attached snapshots.  This is a new setup.   Not sure if the mac address is still in the cache so it is not prompting to re-authenticate.
