I am running the following
NCS shows Controller is not reachable from MSE.
I am able to ping to and from the Controller and MSE.
Sychronization service is showing everything being synchronize. Removed and MSE from NCS and add it back in several times. Not really sure where to go from here.
From https://community.cisco.com/t5/other-wireless-mobility-subjects/controller-keyhash-matches-with-the-mse/m-p/3377668 richard wakefield explains the workaround. enable option 23 on MSE
This fix worked for me. Thanks!
