rabbitmq is also very sensitive to any hostname <-> IP mismatch as it uses this to communicate with the RMQ daemon.

If a "sudo su -" results a warning about hostnames this is def the issue. ** Changed in: rabbitmq-server (Ubuntu) Status: New => Incomplete ** Changed in: rabbitmq-server (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to rabbitmq-server in Ubuntu. https://bugs.launchpad.net/bugs/1783325 Title: Rabbitmq-server times out during server startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rabbitmq-server/+bug/1783325/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
