Problem with z-wave delay after 1-2 days

I have problem with z-wave is getting delayed after couple of days.
When I check the “Z-Wave network viewer” most of the things doesn’t connect directly to the controller but it’s connected in a “singel line”.
I assume that this is the reason I get the delayed.
Do someone know how to fix this?

It would be best to provide a debug log showing what’s happening immediately before and after when the symptoms begin.
