Hi,
I have again (shared previously) started to see lots of "failed to send TCP(read_write) packet (Connection prematurely closed by remote server)".
I am having two instances of Pi-hole on my LAN, on for my wired LAN and one for my wireless LAN, each on different Port and IP address.
Only the Pi-hole that serves the wired LAN shows the message. The wired LAN also got the less clients and activities.
Unbound is running on both Pi-hole instances.
On each I use "Bind only to interface".
FTL log from today morning.

I would suggest running a debug and posting the token. Your log shows the connection errors when using 127.0.0.1:5335 which indicates your using unbound. Have you looked at your unbound config or tried to test unbound as detailed in the guide provide here?
Do you have the same issue if you configure a different upstream resolver instead of unbound?
Thanks.
Both Pi-hole instances are using Unbound.
Both instances of Pi-hole runs on same Raspberry Pi, same Pi-hole versions.
Unbound was installed and setup as per unbound - Pi-hole documentation.
My curiosity is really why one shows the "failed to send TCP(read_write) packet (Connection prematurely closed by remote server)" while the other one don't.
The one that shows got the less activities and clients.
Both Pi-holes runs on own Raspberry Pi 4B+.
Pi-hole token for Pi-hole A which shows the "issue" https://tricorder.pi-hole.net/f1kJG85o/
Pi-hole token for Pi-hole B which don't show the "issue" https://tricorder.pi-hole.net/WKp1LSgj/
Raspberry Pi A runs an instance of the speedtest-tracker app (for years)
Raspberry Pi B runs an instance of the UniFi Network manager (for years)

Pi-hole B
