Unable to load webpage in HA app

I am running Pi.Alert on a Raspberry Pi in my home network and I want to display the web UI in a HA dashboard. I’m using a webpage card to do this. I’m using the card “as is” with no special settings.

When I access Home Assistant with Firefox the card works perfectly. When I access it with the HA app (Android) I get the error:

The web page at http://192.168.1.110/pialert/devices.php could not be loaded because:

net::ERR_TOO_MANY_REDIRECTS

Similarly, when I try to access the dashboard with Chrome I get an error. I’m doing all three on the same laptop.

So… something about the HA app/chrome is creating a loop, probably something in the browser settings. What do I need to change to fix this - is it even possible in the HA app?

Have you examined the web page source?

What should I be looking for?
