I had my Chef server running fine until I changed the static IP address of my virtual machine. When I tried to upload by data bag from my workstation it was failing with the below error ERROR: internal server error Response: Connection failed - user: chef While investigating I found that rabbitMQ service was not started and when I tried to restart the service I got the below error. Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_log, _err rabbitmq-server. ...further investigation I found that in /etc/hosts file there was an entry of my old static ip address against chef server So I changed it to localhost i.e 127.0.0.1 ... then i was able to restart rabbitMQ service and also was able to upload data bags into chef server
