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

Ce message d'erreur apparaît lorsqu'on tente d'apporter des modifications dans la Console Devolutions Server sans pouvoir accéder au fichier `encryption.config` :

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

### Solution

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

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/server/fr/knowledge-base/troubleshooting-articles/maintenance-tool-database-connection-is-invalid.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
