Just to confirm, are you using the latest version of YazFi: v4.2.1? The change log (
see Jack's post one page back) for v4.2.1 indicated that issue was apparently fixed. Basic troubleshooting, do a YazFi force update through the command line console (option: uf). Also try a router reboot after updating YazFi.
Edit: A manual option to try and address the issue was mentioned previously in another thread. See Jack's post in:
host name already in use on macOS with YazFi
Code:
echo "sed -i '/^\[Server\]/a cache-entries-max=0' "'"$1" # '"YazFi" >> /jffs/scripts/avahi-daemon.postconf
service restart_mdns
