# La connexion à la base de données de l'outil de maintenance est non valide

Ce message d'erreur se produit lors d'une tentative de modification dans la Devolutions Server Console alors qu'il est impossible d'accéder au fichier `encryption.config` :

```
Maintenance Tool database connection is invalid
```

### Solution

1. Ouvrez l'invite de commandes et tapez `whoamI`. Il se peut simplement que vous soyez connecté en tant qu'utilisateur sans autorisation d'accès au fichier de chiffrement.
2. Assurez-vous d'avoir l'autorisation ***Lecture*** sur le fichier `encryption.config` situé dans `C:\inetpub\wwwroot\dvls\App_Data`.
3. Une fois l'autorisation correcte accordée, redémarrez la Devolutions Server Console.
