Is there a proper way to increase the heartbeat time or how would I turn it off(would it be wise to) completely? Like I said, tests that are 20+ min seem to lead to a closedconnection error but I've ran plenty of tests from the 1-15 minute mark where everything is fine and the consumer client continues to wait for a message to be delivered. nnection = pika.BlockingConnection(pika.ConnectionParameters('192.168.101.2', 5672, 'user', credentials))

I'm assuming this is due to this code right here and the conflict of heartbeats with the lengthy blocking connection time. Missed heartbeats from client, timeout: 60sĪlso, I receive this error from pika : (-1, "error(10054, 'An existing connection was forcibly closed by the remote host')") In my rabbit logs, I have seen the error closing AMQP connection (192.168.101.2:64855 -> I have noticed that when I run some rather lengthy tests, 20+ minutes, my consumer will lose contact with the producer after it completes it's task.
