Cannot start service we server - Driver failed programming external connectivity on endpoint

Hello,
My server developer is not available right now and we are facing this issue :

There are 5 containers of docker on the server but 3 of them are gone exited just after 1 minute of running the server.

The error thrown by server is:

project-api_redis_1 is up-to-date
project-api_db_1 is up-to-date
Starting 815c75ec40f7_project-api ...
Starting 815c75ec40f7_project-api ... error
