Connecting to MSA not allowing local account with monitor role to connect

When using the connect-hpesan -arraytype MSA
if a local account that is setup with only CLI access and has only the Monitor role, the above connection string will fail with:

WARNING: The Connection was NOT successful.
This is likely due to an incorrect username or password;
Authentication not successful.

Yet, if a putty session is opened to the MSA and the exact same account with the exact same password (password is being copied and pasted to confirm that both uses are correct).

Username has the case being followed in both instances and again, passwords are copied.

PS connection string will fail to connect, Putty session will successfully log in to the MSA in question.

Is there a requirement for the PS commands to have a higher level of role for the user account in order to connect to the MSA unlike with a putty session? Using an administrative role account, the above PS command will connect, but an account with monitor role cannot connect. (reason for using monitor account is simply to run health check show commands through a script for multiple MSAs in quick succession).
