DNS call error: read udp 192.168.91.2:46010->172.64.32.103:53: i/o timeout
Hi Cloudflare, love the services, been a customer since 2015
I use traefik, Two days ago during a reboot I started getting the error in the title while traefik performs a dns challenge to renew the certificate. Haven't changed anything. It has been working flawlessly since 2020. I tried investigating the issue through community, doing some tests, refreshing zone dns token, turning off proxy, turning on dev, turning off ssl. I did various tests with no luck
here is the full error

it happens also with the production server.
Do you know what it could be ?3 Replies
I shall add i checked the propagation with dig, nslookup and whatsmydns.org, i tried a waiting 120 then 300 then 3000 then 8000 seconds before checking. Same result

This may help, they mention that it's strugglign to add a TXT record to cloudflare and the error suggests also, but I may be wrong...
