# Resolve the 'Blocked by runtime' error
Resolve the “blocked by runtime” error in Business Central by enabling Allow HttpClient Requests in Extension Management for the relevant extension.
Outbound HTTP calls from extensions are blocked by default and must be approved for each extension, otherwise instead of an external call, the system will display the following error message:
{% hint style="danger" %}
**Error Message:**
'The request was blocked by the runtime to prevent accidental use of production services'
{% endhint %}
To fix this:
* Navigate to **Extension Management**
* Find the installed extension that is causing the error message
If you are trying to install Configuration Packages the extension is **Base Application**
If you are trying to integrate with Liv-ex the extension is **Bevica Essentials**
Any other scenario please contact your system administrator.
* Click on the **Assist Edit** next to the **Is installed** column
* Select **Configure** and set **Allow HttpClient Requests** to yes.

## 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://kb.bevica.com/documentation/guides/reference/troubleshooting/blocked_by_runtime_error.md?ask=&goal=
```
`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.
