Footer in sensor card not working '404 not found'

Hi,

I have setup 4 sensors but the graph in the footer wont load and got these errors in the browser console, in the home assistant log i found no errors.

Browser error in consol:

status_code: 404
__proto__: Object

Anybody knows whats going wrong?

So nobody has this same issue? The graph footer in the sensor card also does not work in the android app
