```
Unable to login with Microsoft Entra ID. Please contact your administrator. Error: Object reference not set to an instance of an object.
```

### Solution

{% hint style="success" %}
L'URI d'accès est sensible à la casse et doit respecter le nom d'hôte du certificat.
{% endhint %}

Pour résoudre ces problèmes, vérifiez que l'URI d'accès est correctement défini dans l'onglet IIS des paramètres de Devolutions Server. Veuillez consulter [Access URI](https://docs.devolutions.net/fr/server/kb/knowledge-base/access-uri/) pour plus d'informations.
