I'm logged into an Icinga master (Icingaweb2 http interface) as an administrator with "Allow everything (*)" permissions yet when I try to disable passive checks by clicking the Passive Checks checkbox the web interface throws an error:
icinga2: Can't send external Icinga command: 404 No objects found.
