Dear All,
1. Installed OpenStack, accessed Horizon, everything was fine.
2. Router changed server IP and could not access dashboard.
3. Changed SERVERALIAS IP to newly assigned and dashboard login screen appears.
4. Horizon logs show its trying to use previous IP.
Question: when br-ex IP is renewed, how do I refresh OpenStack to use the new IP?, as Horizon cannot be accessed after this change.
$openstack-status : Warning - keystonesrc not sourced.

In principle, br-ex is the bridge by which instances get access to the internet or the network outside of the cloud. It has nothing to do with Horizon.

If your server’s IP address or name changes, you may have to adapt the Keystone catalog, depending on how your system is configured.

Thanks Bernd, ipconfig shows only one IP, that on br-ex, and that's what I have been using to SSH and access dashboard.
Could you kindly explain 'Keystone catalog' please?

The Keystone catalog is the list of the API endpoints of all the services configured in your cloud. You can display it with openstack catalog list or openstack endpoint list. It's also found in Horizon under Access and Security, I think.

Without fundamental knowledge, you won't be able to run, let alone troubleshoot an OpenStack cloud. A number of books are available, as well as some guides on http://docs.openstack.org. I would start with the end-user, admin and perhaps installation guides.

Unfortunately, there is no single user or admin guide anymore. You should get useful information by reading Newton documentation such as https://docs.openstack.org/newton/use... or https://docs.openstack.org/newton/adm....
