# Fejl med ugyldigt certifikat ved opdatering af Remote Desktop Manager

Løs fejlen Invalid certificate ved opdatering af Remote Desktop Manager fra versioner før 2023.2.34 ved at downloade opdateringen manuelt.

Remote Desktop Manager viser fejlmeddelelsen "Invalid certificate", når De forsøger at opdatere fra en version tidligere end 2023.2.34.

Som en sikkerhedsforanstaltning indeholder Remote Desktop Manager en liste over accepterede certifikater for at sikre, at opdateringerne distribueres af Devolutions (en metode, der kaldes certificate pinning).

### Løsning

For at løse problemet skal De manuelt downloade og installere opdateringen via Deres browser.

1. På båndet i Remote Desktop Manager skal De gå til ***Hjælp – Søg efter opdateringer***.
2. På fanen ***Opdatering tilgængelig***, der åbnes, skal De klikke på ***Download*** og derefter på ***Download opdatering ved hjælp af Deres standardbrowser***. Deres browser åbnes, og overførslen bør starte.
3. Når overførslen er fuldført, skal De klikke på den downloadede fil og følge installationsprocessen.

## 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/rdm/da/knowledge-base/troubleshooting-articles/invalid-certificate-error-when-updating-remote-desktop-manager.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.
