[rabbitmq-discuss] can not connect to rabbitmq because pika.exceptions.ProbableAuthenticationError

Mon Sep 16 17:25:36 BST 2013

Hmm. That looks like some problem (in the server) encoding the response 
to connection.start-ok, i.e. connection.tune. Have you customised the 
frame_max or heartbeat setting in the rabbitmq.config file? Can you post 
your config?

Cheers, Simon
