NET 6 API not working when inside a docker container

Question

I'm making a CRUD basic API with the .net 6 basic API template for a class project and it was working perfectly when using it locally, so I tried to dokcerize it since I want to try and upload it to the cloud, but even when giving the enviroment variables for the ASPNETCORE_URLS it won't allow me to connect properly once in the container.

When I have SSL installed it either gives me a connection refused or SSL error, and if I take SSL off it'll give me a 404 error.

I'm a student and I'm just starting with .NET so it might be a dumb error.

The app works as intended when in the container since I tried making a compose with it and it made the migration just fine, I just can't seem to be able to access it from the browser, curl or postman AppSettings.json
