I installed Elasticsearch docker image on windows 10 machine. Docker v4.21.1 and elasticsearch v8.2.2. I downloaded the cert file and running the curl command from same location where file is downloaded. Running below command `curl --cacert http_ca.crt -u elastic https://localhost:9200` I get the below error after entering the password ```auto curl: (60) schannel: CertGetCertificateChain trust error CERT_TRUST_REVOCATION_STATUS_UNKNOWN More details here: https://curl.se/docs/sslcerts.html curl failed to verify the legitimacy of the server and therefore could not establish a secure connection to it. To learn more about this situation and how to fix it, please visit the web page mentioned above. ``` Note: I know insecure options work. But want to understand why it doesn't connect via the secure channel. ---
