This is a bug in the nodejitsu system.
Check to see if the app somehow already exists:

jitsu list

if you see your app is stopped, look at the name of the app, and try:

jitsu apps destroy application-name

If that doesn't work, contact the guys in the #nodejitsu channel on IRC!

Covered this error and others like it in the following blog post: http://raquelvelez.com/blog/2012/03/deploying-to-nodejitsu/

I had the same problem... the reason was that I was logged in by the "wrong user account" --> account is case sensitive --> for example if you have an account Guest with a password you can log in even through guest but the server won't start your application because of an error... so you need to log in exactly as you wrote your account in that case Guest than you are able to do the jitsu deploy command without error normally...

I hope that this answer helped you... just remember account is case sensitive!!!
Thank you
best regards
