# Invalid self-signed certificate in Chrome and Edge

Explains why Chrome and Edge reject older Windows Server self-signed certificates and how to generate a valid one for Devolutions Server.

The default self-signed certificates generated in Windows Server (prior to 2022) are no longer considered valid by Chrome and Edge. For more information for Chrome, see the Google documentation on the [RSAKeyUsageForLocalAnchorsEnabled policy](https://chromeenterprise.google/policies/#RSAKeyUsageForLocalAnchorsEnabled).

### Solution

In Windows Server 2022, you can generate a new self-signed certificate. In older versions, you can use the following PowerShell script to generate a valid self-signed certificate:

```powershell
#Create the cert and place it in the personal cert store
$cert = New-SelfSignedCertificate -DnsName $(([System.Net.Dns]::GetHostByName($env:computerName)).HostName) -CertStoreLocation "cert:\LocalMachine\My" -KeyUsage DigitalSignature,CertSign,CRLSign -KeyAlgorithm RSA -KeyLength 2048 -Provider "Microsoft Enhanced RSA and AES Cryptographic Provider" -NotAfter (Get-Date).AddYears(5)
```

## 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/knowledge-base/troubleshooting-articles/invalid-self-signed-certificate-in-chrome-and-edge.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.
