did you get creds w/ blcred ?
also you didn't supply the role name and auth profile to the blcli command.
Before try AppServerShutdown Command.
First you have to provide the credential with below command.
blcred cred -acquire -profile <profilename> -username <username> -password <password>
then you have set options with below command,
blcli_setoption serviceProfileName <profileName>
blclI_setoption roleName <role>
