If you are unable to access the Odoo server at the URL http://xx.xx.xx.xx:8096 after installing it on a VPS running CentOS, there are a few potential issues that could be causing the problem:

1. The Odoo server may not be running: Make sure that the Odoo server is up and running. You can check the status of the server by running the systemctl status odoo command (assuming that you are using a Linux operating system and have installed the server using the default installation instructions). If the server is not running, you can start it using the systemctl start odoo command.

2. The network configuration may be incorrect: Make sure that the network configuration of the server allows it to connect to the network and listen on the correct ports. You may need to configure the server to listen on the correct IP address and port (e.g., http://0.0.0.0:8096).

3. There may be a firewall or other security software blocking access to the server: Make sure that there are no firewall rules or other security measures that are preventing access to the Odoo server. You may need to configure your firewall or security software to allow access to the server.

4. There may be a problem with the URL: Make sure that you are using the correct URL to access the server. If you are using a domain name instead of an IP address, make sure that the domain name is correctly configured and that it is pointing to the correct IP address.

I hope these suggestions are helpful. If you are still unable to access the Odoo server, please provide more information about your setup and any error messages that you are seeing, and I will do my best to help troubleshoot the issue.
