I am trying to perform Openstack installation on Ubuntu Server 16.04
I am using following scenario.

Host Machine : Windows 7 ( IP : 192.168.1.15) installed VMWare application in it.

Guest Machine : Ubuntu Server 16.04 (IP : provided by VMWare DHCP 192.168.30.178)

Network Adapter : NAT ( VMNet8)

successfully installed openstack on it.

later when I want to access openstack dashboardfrom my host machine (http://192.168.30.178/dashboard) , I changed network adapter of my virtual machine to bridged , so it changes my virtual machine IP address to
( 192.168.1.52)
. so now , when i try to connect http://192.168.1.52/dashboard from my host machine, it open user authetication screen . I entered username as admin and password as mypassword(set by me in local.conf file) But it failed with error Unable to establish connection to keystone endpoint. I checked error log file /var/log/apache2/horizon_error.log , it gives following error

ERROR openstack_auth.plugin.base Unable to establish connection to http://192.168.30.178/identity/v3/auth/tokens : HttpConnectionPool( Host='192.168.30.178' ,port='80')

How did you install OpenStack? If it's Packstack, these instructions indicate it's possible.

Generally, changing addresses requires changes in the depth of OpenStack's databases and is therefore not supported. Here is somebody who seems to have managed this on a Devstack cloud - but over four years ago. This means that your database schema is likely to be different than his.
