Question
I can no longer connect to external URLs after cluster upgrade
I upgraded my k8 cluster a few days ago and since then I have not been able to connect to external URLs.
I am getting a ‘connect timed out’ error when trying to load an external site and locally this same code is running properly.
Do I need to do something special to allow my pod to communicate externally? I messed around with some network policy stuff but that didn’t seem to help.
Could it be related to this change/fix?

Do you see all the pods in your kubesystem running healthy? I would namely look for coredns, kube-proxy, and cilium. If not I would ensure they have enough resources to run reliably and try kicking the pods again. Is the connection issue happening from all nodes?
