404 Page Not Found Error After Installing Frappe CRM on Public IP

[Hbeon]

I have followed the installation instructions provided in the README.md file of the Frappe CRM repository to set up Frappe CRM on my server. However, after completing the installation, I am encountering a "404 Page Not Found" error when accessing the CRM via my public IP address (http://122.180.xxx.xxx:8081). I expected to see the CRM interface, but instead, I get a 404 error, indicating the page cannot be found.
