If only 6789 is actually listening ... and the client tries to connect to 3300 ... you might get a timeout as well. Not sure if messenger falls back to v1. What happens when you change ceph.conf (first without restarting the mon) and try a "ceph -s" again with a ceph client on the monitor node? Gr.
