I'm trying to run appwrite in a self-hosted env with a remote redis and mariadb.

i have edited the .env value like this :

Redis Configuration

_APP_REDIS_HOST=51.75.20.47
_APP_REDIS_PORT=6379
_APP_REDIS_USER=redacted
_APP_REDIS_PASS=redacted

MariaDB Configuration

_APP_DB_HOST=51.75.20.47
_APP_DB_PORT=3306
_APP_DB_SCHEMA=appwrite
_APP_DB_USER=redacted
_APP_DB_PASS=redacted
_APP_DB_ROOT_PASS=redacted

but when i run appwrite doctor i have this :
[Connectivity]
🔴 Console.DB.(console)...........................disconnected
🔴 Projects.DB.(database_db_main).................disconnected
🔴 Cache(cache_redis_main)........................disconnected
🟢 Queue(queue)......................................connected
🔴 PubSub(pubsub).................................disconnected
🔴 SMTP...........................................disconnected

and this error in the logs :
Fatal error: Uncaught Exception: Failed to connect to database: Failed to create connection: ERR AUTH called without any password configured for the default user. Are you sure your configuration is correct? in /usr/src/code/app/http.php:84

If someone can give me an hint about why i can't connect to my remote database and why i got this error ?

Thanks in advance for your support.
