avahi-daemon and dhcpcd are stuck in a loop

Question

My raspberry pi running homeassistant in supervised mode is somehow failing over ever 10-12 seconds. It's asking for a DHCP lease from my router and the logs are spammed. It seems that as soon as the avahi daemon gets a reply, it fails and dhcpd unregisters all IP addresses again restarting the loop anew.

Is there anything I could do to prevent avahi from spamming my log and slowing down my network? Also the logs produced on my OpenWRT router are a mess due to that issue.

Answer 1

Seems like the whole loop was caused by the inability to get an IPv6 address by dhcpcd

This solved my problem (without touching avahi-daemon whatsoever)

Add these lines to /etc/dhcpcd.conf

noipv6rs
noipv6

then systemctl restart dhcpcd.service
