# The specified 'redirect\_uri' is not valid for this client application

Corrige une URI de redirection non valide ou une erreur de connexion Entra ID dans Devolutions Server en corrigeant le paramètre d'URI d'accès, qui respecte la casse, dans IIS.

L'erreur suivante s'affiche lorsque vous tentez de vous connecter sur la page Web de Devolutions Server :

```
error:invalid_request
error_description:The specified 'redirect_uri' is not valid for this client application.
error_uri:https://documentation.openiddict.com/errors/ID2043
```

Lorsque vous tentez de vous connecter à l'aide de l'authentification Microsoft Entra ID dans Remote Desktop Manager, vous pourriez plutôt obtenir le message d'erreur suivant :

```
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 respecte la casse et doit respecter le nom d'hôte du certificat.
{% endhint %}

Pour résoudre ces problèmes, vérifiez que l'URI d'accès est correctement configuré dans l'onglet IIS des paramètres de Devolutions Server. Veuillez consulter [URI d'accès](/server/fr/knowledge-base/knowledge-base-articles/access-uri-format.md) pour plus d'informations.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/server/fr/knowledge-base/troubleshooting-articles/the-specified-redirect_uri-is-not-valid-for-this-client-application.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
