Answer: C

Explanation:

If you’re running Vault in a non-prod environment, you can configure Vault to disable TLS. In this case, TLS has been disabled but the default value for VAULT_ADDR is https://127.0.0.1:8200, therefore Vault is sending the request over HTTPS but Vault is responding using HTTP since TLS is disabled.

To handle this error, set the VAULT_ADDR environment variable to "http://127.0.0.1:8200".
