Connection refused

[truckee]

I've installed eko/docker-symfony in WSL2/Ubuntu-20, along with a working Symfony project in dev mode. On launching http://symfony.localhost/ I get a MySQL

An exception occurred in driver: SQLSTATE[HY000] [2002] Connection refused

The exception is thrown in an entity's repository:

        $fileNames = $this->createQueryBuilder('f')
                ->select('f')
                ->orderBy('f.filename', 'DESC')
                ->getQuery()
                ->getArrayResult()
        ;

Edit: (logs available after docker-compose down & docker-compose up).

Stuck dd($params) in Doctrine\DBAL\Driver\PDOMySql\AbstractMySQLDriver and got this:

Driver.php on line 22:

  "url" => "mysql://symfony:symfony@127.0.0.1:3306/rv?serverVersion=8.0"

From logs/nginx:

After installing MySQL client in WSL/Ubuntu:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

In PowerShell:

ERROR 1045 (28000): Access denied for user 'symfony'@'172.27.0.1' (using password: YES)

Edit:
docker-compose exec db mysql -u root -p allows connection.

Should have found issue at #83.
