    NT8 Login issues with TD Ameritrade

    Hello,

    I've started receiving the following error message while logging into NT8 starting late last week. It was working all fine before then. I've subscription to Level II data from TD Ameritrade already. Any pointers or suggestion if I'm missing out something there?

    Error: Unable to login in. WARNING: 3 INVALID LOGIN ATTEMPTS IN A ROW WILL LOCK OUT THE ACCOUNT! Error message from TD AMERITRADE: Source is not Whitelisted (Logon failed)

    Thanks in advance!
