# Maintenance Tool database connection is invalid

This error message occurs when trying to make changes in the Devolutions Server Console while being unable to access the `encryption.config` file:

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

### Solution

1. Open command prompt and type `whoamI`. It might simply be that you are connected as a user without permission to access the encryption file.
2. Make sure you have the ***Read*** permission on the `encryption.config` file located in `C:\inetpub\wwwroot\dvls\App_Data`.
3. Once the correct permission has been granted, restart the Devolutions Server Console.
