Rest API url not working!!!

[vanabdes]

Despite diligently following the Docker tutorial and successfully setting up Metasfresh using Docker, I'm encountering an issue with the API URL. While the UI URL functions properly and all containers are running within Docker, the API URL remains problematic.

error:

here is my docker-compose.yml
