Not sure if this is issue with client id, but you can easily verify it by running on server:
mminfo -avot -q client=<NSR client> -r clientid | sort -Unique
(last part above makes sense if using powershell in Windows env)
If you have just one, then:
recover -s <server> -d <somewhere> -S <ssid> is all you need.
I do not understand why you run scanner nor why you used tape name in recover example. Of course, if you want to recover something specific from ssid, you need to add path of that at the end (be aware it is case sensitive).
