Seems like a problem with iframe's Clickjacking Protection. The Django docs say:

By default, the middleware will set the X-Frame-Options header to DENY for every outgoing HttpResponse. If you want any other value for this header instead, set the X_FRAME_OPTIONS setting.

Try this setting in order to allow iframes from the same ip addres as the main page:

X_FRAME_OPTIONS = 'SAMEORIGIN'

You can read more at: https://docs.djangoproject.com/en/4.0/ref/clickjacking/#setting-x-frame-options-for-all-responses
