Unable to reach ip from kubernetes pod but can access it from underlying server

Question

I am able to hit the ip from the server on which the pod is running wget https://10.64.2.21 - https://10.64.2.21/ Connecting to 10.64.2.21:443... connected.

But not from within the pod ➜ ~ k exec -ti debug /bin/sh / # wget https://10.64.2.21 Connecting to 10.64.2.21 (10.64.2.21:443)
