Hi ,

Sorry its working fine it was proxy issue. 😃 Thanks for all the support

Faced the same issue, there were http_proxy and https_proxy set in the pod. After resetting these proxies the error was resolved.

How to reset the proxy？

Resetting the http_proxy and https_proxy in the Kubernetes pod can be done by setting value of HTTP_PROXY and HTTPS_PROXY to null. This can be done in the corresponding deployment file by adding 2 variables in the env.

The following is an example that worked for me:

spec:
  template:
    spec:
      containers:
        env:
        - name: HTTP_PROXY
          value: null
        - name: HTTPS_PROXY
          value: null

This can be further verified by doing exec into the pod and running the following command:


export | grep "HTTP_PROXY"
export | grep "HTTPS_PROXY"

Thanks and Regards, Vijit
