Can't connect to the app no matter what. Deployed through Docker.

[Jas-SinghFSU]

No matter what I do, I can't access the server. I get connection timeout errors or "refused to connect" errors. My server's local IP address is 10.0.0.239 and that's the address I want to host it at.

No matter what I do, the log for the container says

Ready on http://localhost:3030

Even though I never specified localhost as the domain, it always tells me that the app is read on localhost:3030. I have tried to access localhost:3030 on my server and still get 'The site can't be reached'. I also have my own subdomain.domain.com but when I put that into the DEFAULT_DOMAIN it doesn't work either.

Here are my configs, what am I doing wrong?

DEFAULT_DOMAIN should be 'subdomain.domain.com'
Do you have reverse proxy set up?
