# Remove Self-Signed Certificate Error
Parallels Remote Application server comes preconfigured with a self-signed certificate to enable SSL access to the Farm during the testing phase. Self-signed certificates will generate a warning that the connection is not secure/private. For production purposes, certificates should be purchased from a Certificate Authority.
During the testing phase you may wish to suppress the self-signed certificate error which can be done using RAS Policy settings. Note that this policy only works with Parallels Client for Windows, Mac, and Linux.
To remove the certificate error simply follow the steps below:
1. Navigate to **Policies** from within the RAS Console.
2. Click 
to add a Local/Domain group which will be affected by this policy.
3. Select **Options** under **Policy**.
4. Then click on the **Advanced Settings** tab.
5. Check the option **Do not warn if server certificate is not valid**.
6. Click **OK** and then **Apply Settings**.

## 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.parallels.com/landing/ras-best-practices-guide/v20/miscellaneous/remove-self-signed-certificate-error.md?ask=&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.
