Failing docker pulls/run

I am experiencing issues that are beyond my abilities. I am running a homelab with ubuntu server 22.10 and docker. All was working well but yesterday evening I encountered a strange issue. When attempting to docker pull I am greeted with this; " Using default tag: latest
Error response from daemon: Get “”: dial tcp: lookup on [::1]:53: read udp [::1]:39271->[::1]:53: read: connection refused"

Any help much appreciated

-Thanks in advance!
