and peer network config:

cat /proc/sys/net/ipv4/ip_forward
1

Both server and peer are Ubuntu 22.04 and both sides run through:

wg-quick up wg0

on the server side when I enable log by:

echo "module wireguard +p" | sudo tee /sys/kernel/debug/dynamic_debug/control

I get almost nothing about wireguard but when I enable logging in peer using:

sudo dmesg -wT

I get these messages and after 20 attempts it says given up!

I followed instructions based on this guide: here

double-checked everything and also regenerated keys again but the same result. Any idea? Thanks in advance.
