If you are Experiencing issues with a Pi-hole install that has non-standard elements (e.g you are using nginx instead of lighttpd, or there is some other aspect of your install that is customised) - please use the Community Help category.
Expected Behaviour:
No errors in system
Actual Behaviour:
DNSMASQ_WARN reducing DNS packet size for nameserver 1.1.1.1 to 1280
Those kind of errors have received elevated visibility with recent Pi-hole releases, although they'd always been properly logged on occurence before (likely without anyone noticing them).
reducing DNS packet size for nameserver ADDRESS to SAFE_PKTSZ
When receiving answers from upstream only with a smaller maximum DNS packet size, dnsmasq warns about this and remembers this decision per server for some time (defaulting to 60 seconds).
If you see this message continuously, you are affected by some unusual truncation on the path from your Pi-hole to the configured upstream server. You can get rid of the warning by adding a config file like /etc/dnsmasq.d/99-edns.conf and adding
edns-packet-max=1232
After running pihole restartdns your Pi-hole will not even try larger packet sizes (the default is 4096). Check out our unbound guide for a comment about the particular value of 1232 .
