+shop is running under a custom domain, you need to add the following rules:
+
+* ``script-src``: ``'unsafe-eval' https://pretix.eu`` (adjust to your domain for self-hosted pretix)
+* ``style-src``: ``https://pretix.eu`` (adjust to your domain for self-hosted pretix **and** for custom domain on pretix Hosted)
+* ``connect-src``: ``https://pretix.eu`` (adjust to your domain for self-hosted pretix **and** for custom domain on pretix Hosted)
+* ``frame-src``: ``https://pretix.eu`` (adjust to your domain for self-hosted pretix **and** for custom domain on pretix Hosted)
+* ``img-src``: ``https://pretix.eu`` (adjust to your domain for self-hosted pretix **and** for custom domain on pretix Hosted) and for pretix Hosted additionally add ``https://cdn.pretix.space``
