Hi, It fails because of the wget in busybox. wget can't handle HTTPS requests for kubernetes.io properly.

$ kubectl run bbox --image=busybox --restart=Never -it -- /bin/sh
 # wget http://kubernetes.io
Connecting to kubernetes.io (147.75.40.148:80)

wget: note: TLS certificate validation not implemented
wget: TLS error from peer (alert code 80): 80
wget: error getting response: Connection reset by peer

But it works for other websites like gnu.org

/ # wget -O index.html https://gnu.org

There is a PR at https://github.com/dgkanatsios/CKAD-exercises/pull/136/files about updating kubernetes.io with a working site.
