Pgbouncer is running, but cannot connect

I started pgbouncer as "pgbouncer -d pgbouncer.ini"

tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN -

tcp 0 0 127.0.0.1:5433 0.0.0.0:* LISTEN 28912/pgbouncer

But I cant connect postgres as "psql -p 5433 postgres". Also tried as "psql -d pgbouncer -U postgres -p 5433".

Any solutions?
