Connection problem

[GADET2023]

I have been using NinjaTrader for nearly a month. I feel very comfortable with it. However, last night my intertnet service failed. When restored, I could not activate my NinjaTrader and I am repeatedly getting this message: "My Rithmic for NinjaTrader Brokerage: Please check your account connection parameters and internet connection. (Logon failed)".
I have spent several hours trying to solve this problem with no success. Can anyone help me?
Thank you

Rithmic was down yesterday. It is back up.
