# Why doesn’t the Portainer UI load inside an iframe?
By default, Portainer cannot be embedded in an iframe. This is because the default **Content-Security-Policy (CSP)** header includes:
```
frame-ancestors 'none';
```
This blocks all iframing of Portainer.
If you need to allow iframing, you can disable the CSP header entirely by setting the [`--no-csp` flag](../../advanced/cli.md#configuration-flags-available-at-the-command-line) when running Portainer. 
{% hint style="danger" %}
This removes **all** of the Content-Security-Policy header, so please use it with caution and at your own risk, and only if you **need** the iframing to work for you.
{% endhint %}
