The “invalid account” / “authorization failed” / “unauthorized” error messages are encountered when you enter your password incorrectly or when you select the wrong server.
Please make sure you select mt4.sageFx.com (SageFX Live) as the server when logging in to a Live Account. For your Demo Account, the selection should be demo.SageFx.com (SageFX Demo)
If the server selection is not the issue, please try resetting your MetaTrader password. This can be done from the “My Accounts” section.
Step by step guide:
Click "My Accounts"
Click "View" on the account in question
Click "Copy" to copy the password and click "Submit" on the system generated password
