Nope. Coredns logs are ok: 2019-07-26T19:53:18.670Z [INFO] CoreDNS-1.3.1 2019-07-26T19:53:18.670Z [INFO] linux/amd64, go1.11.4, 6b56a9c CoreDNS-1.3.1 linux/amd64, go1.11.4, 6b56a9c 2019-07-26T19:53:18.670Z [INFO] plugin/reload: Running configuration MD5 =

and 0 restarts.

Hi there!

Do you see any logs in the coredns pods or any restarts on the coredns pods themselves?

I am running into the same issue on DOKS. What version did you upgrade/downgrade to?

Not sure of the information about your upgrade, the issue seems to be due to kube-dns version resolving external name services. You have to roll back kube-dns to a previous build or upgrade to.

OR try to check if your kube-dns version changed whenever you upgraded your OS.
