Hello.

Looking at the error text and the source location, I'd guess that either you're not able to correct resolve "rabbitmq" or your RabbitMQ instance isn't running. From a shell, try running a:

ping rabbitmq

If it doesn't at least give you an IP that it is attempting to connect to then name resolution is failing. (Did you perform our hosts file configuration?) If you do at least see an IP and it doesn't connect, then you might have a firewall issue. I note that 5671 is the rabbitmq port, not 15672. 15672 is the UI interface for rabbitmq management, Polar doesn't use this port.

In either case, we should do better to output a more friendly error message on connection failure and exit gracefully, instead of panicking.
