 - You can not dot HA SSO mode  and or limited to N+1 high availability , meaning that the list of available controllers is configured on the access points.

Just to add, we don’t know what model or version you are running, but both should be on the same version. Please revive the N+1 guide.  this should help you understand what is required and how it should be setup.
