I am getting node down error on rabbitmq, this is happening sometimes.
Able to see the below error when I execute:
sudo rabbitmqctl status or
sudo rabbitmqctl list_queues
Error: unable to connect to node : nodedown connected to epmd (port 4369) on host-name epmd reports node 'rabbit' running on port 25672 can't establish TCP connection, reason: timeout suggestion: blocked by firewall?
We are using open-release/hawthorn.master of open edX, native installation.
What could be the reason behind this error and possible solution?
I have also posted question on Stack Overflow, which you can find here.
Please help me with this.
