I have a scenario where I was using `curl --noproxy "*" https://..` to get the response but suddenly when I use it now it doesn't return me the response instead it says

```
curl: (60) Peer certificate cannot be authenticated with known CA certificates
More details here: http://curl.haxx.se/docs/sslcerts.html

```

now when I use `curl -k https://` it gives me response.
I am not sure what went wrong and what could be the cause for this.

Any idea how to not use `curl -k` insecure option ?
