While trying to establish trust between the Network Security Manager and the IPS sensor the set sensor sharedsecretkey command is producing the following error and will not allow the key to be entered.
This image mandates RSA 2048-bit compliance. Please check network reachability and service for RSA 2048-bit support on NSM.
It was allowing the key to be entered prior to a reboot. The sensor would just never initialize after that even though the alert, log and auth channels were up.
Below are the results of the Show and Status commands.
