Unable to access ossinsight on cloud server via web browser

[kubetoolsio]

Tried setting up ossinsight over the cloud server instance.

 clone the repo
 npm install
 npm start

The command executed successfully and I am able to access it via terminal but unable to access it via web browser.
Steps I tried:

1. Tried disabling firewall
2. Tried running a nginx service on 3001 to see if firewall port isse, but I was able to access localhost:3001

Also, would love to know how you're passing environmental variable if I use docker compose file. I do ETL_DATABASE and API related environmental variable that needs to be passed.

Please suggest.
