I use twrl and I authenticate from command line
twurl authorize -u <usr> -p <pass> --consumer-key <key> --consumer-secret <secret>
I typed te PIN and i saw the message "Authentication successful"
Then if execute
twurl -t -d track=#RealMadrid -H stream.twitter.com /1.1/statuses/filter.json
The response is:

Why is this happening? If I authorizated before…
I am doing something wrong?
Thanks!
