Ok so, I think it was running on the wrong node and using thats resolv.conf which I did not update, but I am getting a new issue:

kube-dns usually isnt supposed to give a i/o timeout when going to external domains, im pretty sure its supposed to forward it to another dns server, or do i have to configure that?

Nevermind, fixed, this is what I tried applying, or maybe i should have waited for a bit and it might of worked, regardless, just incase its useful to anyone:

apiVersion: v1
kind: ConfigMap
metadata:
  name: coredns
  namespace: kube-system
data:
  Corefile: |
    .:53 {
        errors
        health
        ready
        kubernetes cluster.local in-addr.arpa ip6.arpa {
            pods insecure
            fallthrough in-addr.arpa ip6.arpa
        }
        hosts /etc/coredns/NodeHosts {
            ttl 60
            reload 15s
            fallthrough
        }
        prometheus :9153
        forward . 1.1.1.1 1.0.0.1 8.8.8.8 8.8.4.4
        cache 30
        loop
        reload
        loadbalance
    }

The issue is solved now, thanks

That’s from a disconnected Cloudflare tunnel connection. Are you trying to run Cloudflare Tunnel inside your cluster for some reason?
