# Aktualisieren Sie alle Duo-Apps und -Clients bis zum 2. Februar 2026, um Dienstunterbrechungen zu vermeiden

Am 2. Februar 2026 hat Duo auf ein neues Certificate Authority (CA)-Pinning-Bundle umgestellt. Infolgedessen können bei Benutzern von Remote Desktop Manager und Devolutions Server, die die Duo-Authentifizierung nutzen, Kompatibilitätsfehler auftreten.

{% hint style="info" %}
Weitere Details finden Sie in der [Dokumentation von Duo](https://help.duo.com/s/article/9451?language=en_US).
{% endhint %}

### Lösung

Um die Dienstkontinuität sicherzustellen, aktualisieren Sie auf die folgenden Versionen:

* Remote Desktop Manager Windows: 2025.3.29.0 oder höher
* Remote Desktop Manager macOS: 2025.3.29.0 oder höher
* Devolutions Server: 2025.3.14.0 oder höher. Um bei Devolutions Server Version 2025.2 zu bleiben, aktualisieren Sie auf 2025.2.22.0, um den Duo-Fix zu erhalten.

Dadurch wird auch die Warnung entfernt, die im Duo-Portal im Bereich ***Reports*** – ***Unsupported Clients Log*** angezeigt wird.

## 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/rdm/de/knowledge-base/troubleshooting-articles/update-all-duo-apps-and-clients-by-february-2-2026-to-avoid-service-disruption.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.
