OSError 105 : No buffer Space – Zeroconf

I’m using a NanoPi M1 (Allwinner H3 board) & running a Yocto-based OS. On my first encounter with ZeroConf-python, I’m getting the error: This error doesn’t arise when I run it in Raspbian(on RPI). I’ve tried to search for fixes to such errors in homeassistant, but none provide a good overview to the real problem, rest-aside the solution. Answer Update the net/ipv4/igmp_max_memberships value of sysctl to greater than zero. Execute the following commands on the terminal: $ systctl -w net.ipv4.igmp_max_memberships=20 (or any other value greater than zero) & $ sysctl -w net.ipv4.igmp_max_msf=10 Then, restart the avahi-daemon systemctl restart avahi-daemon You
