Description manisha 2020-07-14 15:16:16 UTC

Description of problem: 

Facing issues while authenticating to the cluster and could observe below error and oc binary not working as well.

---
F0714 07:22:20.965587  720050 helpers.go:114] Error from server (InternalError): Internal error occurred: unexpected response: 400
---

While investigating the issue it was identified that there is an issue with proxy in the cluster. When checked env variables configured for proxy in the crictl config file those seemed ok. however, the curl request was going through 
  proxy instead of noproxy configured for internal communication in the cluster.

The NO_PROXY variable is not picking up CIDR range however when individual IP is given it successfully takes up the IP address.


Version-Release number of selected component (if applicable): 4.4.10


How reproducible: Always.
