# Problem bei der Verwendung der Devolutions Password Manager Browser-Erweiterung mit localhost über HTTPS

Beheben Sie Verbindungsfehler der Devolutions Password Manager-Browsererweiterung zu localhost über HTTPS, die durch HSTS-Preload verursacht werden, mithilfe von Native Messaging oder durch Entfernen

Die Devolutions Password Manager-Browsererweiterung unterstützt keine Verbindung zu Remote Desktop Manager über HTTPS. In Devolutions Password Manager können Verbindungsprobleme auftreten, wenn die HSTS-Preload-Konfiguration Ihres Systems localhost enthält.

Um zu prüfen, ob Devolutions Password Manager versucht, eine Verbindung über HTTPS herzustellen, [untersuchen Sie den Netzwerk-Tab Ihres Browsers](/password-manager/de/knowledge-base/browser-extension-knowledge-base/devolutions-password-manager-browser-extension-troubleshooting-connection-logs.md). Die fehlgeschlagene Anfrage an HTTPS sollte in Rot angezeigt werden.

### Lösung

Verwenden Sie entweder die [Devolutions Password Manager-Browsererweiterung über Native Messaging](/password-manager/de/knowledge-base/browser-extension-knowledge-base/devolutions-password-manager-browser-extension-via-native-messaging.md) oder entfernen Sie localhost aus Ihrer HSTS-Liste.

{% hint style="info" %}
Da localhost standardmäßig nicht Teil der HSTS-Liste ist, muss es von einem System- oder Netzwerkadministrator zu einem bestimmten Zweck manuell hinzugefügt oder vorab geladen worden sein. Das Entfernen könnte zu unvorhergesehenen Folgen führen.
{% endhint %}

## 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/password-manager/de/knowledge-base/browser-extension-knowledge-base/issue-using-the-devolutions-password-manager-browser-extension-with-localhost-with-https.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.
