Error connecting to database through Docker

I have a mysql service running on port 3308 using docker. However on table plus when I try to access this using “127.0.0.1” as the Host and Port “3308”, enter the user, password and database name if I test the connection it shows an error:

Lost connection to MySQL server at 'reading initial communication packet', system error: 0

Also If I run php artisan migrate I get:

 Illuminate\Database\QueryException

  SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO) (SQL: select * from information_schema.tables where table_schema = project and table_name = migrations and table_type = 'BASE TABLE')

    714▕             );
    715▕         }
    716▕     }

If I use the port 3306 on tableplus I can connect to the database but still get the issue with the php artisan command. But it's strange because in docker is configured with port 3308.

.env:

DB_CONNECTION=mysql
DB_HOST=host.docker.internal
DB_PORT=3308
DB_DATABASE=project
DB_USERNAME=root
DB_PASSWORD=pass

Do you know what can be the issue?
