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

Retter en ugyldig omdirigerings-URI eller en logonfejl med Entra ID i Devolutions Server ved at rette den versalfølsomme indstilling for adgangs-URI i IIS.

Følgende fejl vises, når De forsøger at logge på websiden for 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
```

Når De forsøger at logge på med godkendelse via Microsoft Entra ID i Remote Desktop Manager, kan De i stedet få følgende fejlmeddelelse:

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

### Løsning

{% hint style="success" %}
Adgangs-URI'en skelner mellem store og små bogstaver og skal stemme overens med certifikatets værtsnavn.
{% endhint %}

For at løse disse problemer skal De kontrollere, at adgangs-URI'en er angivet korrekt under fanen IIS i indstillingerne for Devolutions Server. Se [Format for adgangs-URI](/server/da/knowledge-base/knowledge-base-articles/access-uri-format.md) for at få flere oplysninger.

## 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/da/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.
