maas fails because rabbitmq does not update new MAAS address

[Tranhoangdainguyen]

so by some mistake, when I install maas from cd, i enter the wrong static ip (connect to internet) on the eth0,
thus I cannot connect to the MAAS GUI, it shows internal error page

something like this:
correct: 163.180.117.47
wrong enter: 163.180.177.47 (so it should be 117)

after the os installation, i quickly go and use to fix the correct ip
1 - sudo dpkg-reconfigure maas-cluster-controller (http://192.168.117.47/MAAS)
2 - sudo dpkg-reconfigure maas-region-controller (http://192.168.117.47 )

When I issue command 1, it shows apach2 restart normally
But when I issue command 2, it shows rabbit mq error, and rabbitmq still using the wrong ip address.

here is the log from celery-region.log

This is NOT a duplicate of bug #1300507. It has nothing to do with changing the RabbitMQ password!
