SSH Help

I am trying to install Nitotv onto my apple tv2 via terminal. I used to be able to do it and now when I type in the root and ip address it no longer asks for the alpine password.

I tried installing the nito installer to my computer however in the drop down bar I cannot pic and apple tv. its like it doesnt find the apple tv.

I have tried to do resets of everything… rejailbroke the apple tv and still nothing. If someone has any information on how to fix the SSH that would be a great help

Thank you
