503 Service Unavailable Error while hosting Django website on CyberPanel

I am trying to host my Django website using CyberPanel on OpenLiteSpeed.
I have completed website development. The website is running properly when I run in debug mode (using runserver command). I am trying to deploy the website.

I am using CyberPanel as I wish to deploy my own SMTP server.

I have used the following article to install cyber-panel on my digital ocean server : 01 - Installing CyberPanel - Docs - CyberPanel Community

I have used the following article to install and configure Django based website on Openlitespeed server How to setup DJANGO application on CyberPanel/OpenLiteSpeed - #2 - Blog Posts - CyberPanel Community

When I try to open website unionelectronics.in I get 503 Service Unavailable (The server is temporarily busy, try again later!) error.

I have updated A record in DNS Management on godaddy to point to my cloud service provider (digital ocean).
