iFrame HTTPS/SSL warning

Hi, everyone

I have created a PRTG monitoring map and would now like to display it on an iFrame card.
On the PC it works without any problems IF I confirm this HTTPS/SSL message with “Visit this website anyway” Before that I only get a black card.
It also works on the iPad in the browser if I have confirmed the HTTPS/SSL message beforehand.
In the HA app I only get a black card because I can’t confirm this message here. How can I solve this problem ?

You cannot view http websites as an iframe inside https page (without warning) and mobile apps are much more strict on this, so, not doable.

But i have seen some examples, people are creating local pointers inside home assistant webserver which is fetching and serving http in background.

You night use nginx proxy and fetch http endpoint and serve it via nginx https. Example: Home Assistant panel_iframe access with nginx proxy - iotechonline

I have created a corresponding certificate with letsencyrpt and now everything works
