Calling a SQL SP from VB.NET and it fails on the .ExecutNonQuery method of my routine

Below is both the SQL Stored Procedure and VB.NET Code:
--- SQL SP Code ---
SET ANSI_NULLS ON
SET QUOTED_IDENTIFIER ON
GO
 
ALTER PROCEDURE [dbo].[ADScan_CheckIfWkstnIsDisabled]
  @Workstation_Name varchar(MAX),
 @Status varchar(11) OUTPUT
AS
BEGIN
--  DECLARE @Status varchar(11)
--  Set @Status = 'Disabled'
  SELECT U.Status, N.Workstation_Name
  From Uptime U INNER JOIN Network N ON U.Mac=N.Mac
  WHERE U.Status = @Status And N.Workstation_Name = @Workstation_Name
END
--- VB.NET CODE ---
'Check first to see if the workstation is already disabled. If it is, exit While loop.
                        Dim cmdGetStatus As New SqlClient.SqlCommand("ADScan_CheckIfWkstnIsDisabled", sqlCon)
                        cmdGetStatus.CommandType = CommandType.StoredProcedure
                        'sqlCom.CommandText = "ADScan_CheckIfWkstnIsDisabled"
                        Dim parmStatus As SqlClient.SqlParameter = cmdGetStatus.CreateParameter
                        Dim parmWkstn As SqlClient.SqlParameter = cmdGetStatus.CreateParameter
                        With parmWkstn
                            .ParameterName = "@Workstation_Name"
                            .SqlDbType = SqlDbType.VarChar
                            .Direction = ParameterDirection.Input
                            .Value = host
                        End With
                        With parmStatus
                            .ParameterName = "@Status"
                            .SqlDbType = SqlDbType.VarChar
                            .Direction = ParameterDirection.Output
                        End With
                        cmdGetStatus.Parameters.Add(parmWkstn)
                        cmdGetStatus.Parameters.Add(parmStatus)
                        cmdGetStatus.ExecuteNonQuery()
 
                        Return (parmStatus)
