Error on _myapp_provision?username=user&password=pword

[v3yr0n]

I'm getting this error when I try the _myapp_provision?username=user&password=pword2 url.
{
error: "error",
reason: "{conn_failed,{error,econnrefused}}"
}

Any idea?
I think that maybe something is not right on my setup. Where should i add the provision.js file?
I'm using couchdb 1.6.1.

Thanks!
