Subject Re: [SOLVED] No response received when trying to login
Date Mon, 20 Apr 2015 07:29:25 GMT
This is a known issue with ACS 4.3, where ACS becomes unresponsive/stuck if RabbitMQ is not
running or if both RMQ broker and ACS plugin are not correctly configured.

I’m not sure about 4.4, but with 4.5+ in case RabbitMQ server is not running or the plugin
is not correctly configured, ACS will add error logs that it was unable to publish events
on the event bus (rabbitmq).
