    Try this:

     

    config t

    logging level debugging security subcat aaa

    Try logging in and after you try and it fails, type:

     

    show log security 50

     

    That might give you an idea of what is wrong...

    According to the logs your controller/TACACS server doesn't like the MSCHAP authentication method. Can you try disabling MSCHAPv2?2017-12-04 16_17_05-Management Administration Configuration.png

    It looks like only RADIUS is compatible with MSCHAPv2 for management login.
