# Known issues with NEAT

> Known issues and workarounds when using NEAT, including ad-blocker conflicts and NeatSession initialization errors.

This page documents known issues and workarounds when using NEAT.

<AccordionGroup>
  <Accordion title="Ad-blockers causing NeatSession initialization errors" defaultOpen={true}>
    When initializing a `NeatSession`, you may encounter the following error if you have ad-blockers enabled:

    ```python wrap theme={"languages":{"custom":["/_languages/kuiper.json","../_languages/kuiper.json"]}}
    ProtocolError: ('Connection aborted.', HTTPException('Failed to fetch'))
    MaxRetryError: HTTPSConnectionPool(host='api-eu.mixpanel.com', port=443): Max retries exceeded with url: /engage (Caused by ProtocolError('Connection aborted.', HTTPException('Failed to fetch')))
    ```

    **Cause**: This error occurs because NEAT attempts to send anonymous usage analytics to Mixpanel, but ad-blockers prevent the connection.

    **Solution**: Disable your ad-blockers or add mixpanel.com to the allowlist in your ad-blocker settings.
