I have a code to connect to a server to get an image. It is working fine on the local host, but when I host my web app to azure and try to call the same server, I get this Error: getaddrinfo ENOTFOUND error. If I change the host name in the url to ip address, I am getting a certificate error. Any inputs would be of great help

I have created a PostgreSQL with a web server DOCKER CONTAINER and my app running with an API to manage all the endpoints.
The link of my git repo is: https://github.com/JulioValderrama/store-front-project.git
But I am facing problems with the connections with the Database, as depending on the Postgres HOST name value in my .env file one of the two servers (one local running in PORT 4000 and the web server running in the docker container in PORT 3000) will work or will fail.
I have tried the next:
Local server running in PORT 4000
Docker web server running in PORT 3000
HOST "127.0.0.1"
Going to¨:
http://localhost:3000/
Works fine and get response, now when trying to connect it to any of my database API:
http://localhost:3000/products
I get the error:
"Could not get PRODUCTS. Error: Error: connect ECONNREFUSED 127.0.0.1:5432"
Going to:
http://localhost:4000
Works fine and get response, now when trying to connect it to any of my database API:
http://localhost:4000/products
It works! I get the list of all my products!!
HOST "postgres"
I put "postgres" because I read online that you have to name HOST as the postgres docker image created, which is my case. And it works for the remote server.
Going to:
http://localhost:3000
Works fine and get response, then when trying to connect it to database API:
http://localhost:3000/products
It works!! It gives me the list of my products !!
Going to:
http://localhost:4000
Works fine and get response, then when trying to connect it to database API:
http://localhost:4000/products
It gives me the error:
"Could not get PRODUCTS. Error: Error: getaddrinfo ENOTFOUND postgres"
So it seems like there is an error when trying to connect to the database due to the server or the HOST name, I have no idea....
In docker-compose.yaml you have linked your machine 5432 to containers 5432 port.
If you are using docker container and want to reach postgres, use postgres as POSTGRES_HOST value.
If you are running application outside the docker environment use 0.0.0.0, 127.0.0.1.
Make sure you haven't installed postgres locally
brew uninstall postgres

For a custom docker image, you need include port 2222 in the EXPOSE instruction for the Dockerfile. Although the root password is known, port 2222 cannot be accessed from the internet. It is an internal only port accessible only by containers within the bridge network of a private virtual network.
EXPOSE 2222 80
More information about this please refer to this link.
You also could check this dockerfile.
