AdguardHome + Unbound unstable connections and cannot load websites sometimes

I found this thread because I was looking for someone who also had tcp-timeouts with pi-hole+unbound. My log often shows this error message:

Connection error (127.0.0.1#5335): TCP connection failed while receiving payload length from upstream (Connection prematurely closed by remote server)

Is there a problem with the combination of pi-hole+unbound?

not I’m aware of, running fine on my side. I doubt your problem is related to the topic above.

This issue is very similar if not the same as the one I have.
