Issues with weekly summaries

Good evening,

I consistently receive a message in the weekly summary indicating that a camera is silent. This has been the case for 15 months now.

However, the camera is functional and the images appear in Gladys.

Another observation:
I requested a report on the cameras in the discussion, but only 3 out of 5 were listed.
It also states that a camera is not responding, even though the stream is available.
