TLS issues PROD

[creativehubspace]

I have a domain registered in Cloudflare. I have disabled both proxy and SSL/TLS encryption in my Cloudflare dashboard for the domain. When I try to start my app in production mode, I keep getting the following error. What could be the issue?

I had forgotten to add an A record for my server IP in cloudflare.
