I can connect to de database using docker exec and using dbbeaver-ce but when I try to execute php bin/console make:migrations on the php container I get this error message

[critical] Error thrown while running command "make:migration". Message: "An exception occurred in the driver: SQLSTATE[HY000] [2002] Connection refused"

this is the connection url on .env file

DATABASE_URL="mysql://root:root@127.0.0.1:3306/user_database?serverVersion=8.0.39&charset=utf8mb4"

I changed the doctrine entity mapping to xml but it sholdn't be the problem.

Inside docker, the container name is used instead of 127.0.0.1. In your case, it is root:root@mysql:3306/...
