Mysql connection refused after upgrade to Ynh 4.1

followoing this thread, I see that my “GRANTS” use socket rather than password :face_with_monocle: :

MariaDB [mysql]> SHOW GRANTS;

| Grants for root@localhost                                                                                                                        |
+--------------------------------------------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO `root`@`localhost` IDENTIFIED VIA unix_socket USING '*2C99EAB56A508DC87D6701B6359195FF0A43B832' WITH GRANT OPTION |
| GRANT PROXY ON ''@'%' TO 'root'@'localhost' WITH GRANT OPTION      

Is this a normal status ?
