Hello,

I am trying to setup a HTTPS on NiFi Registry and am receiving SSL_ERROR_BAD_CERT_ALERT when attempting to access the URL after loading the certificates.

The way I am setting it up is that I create a CSR, have the CA sign it (AD Domain Controller) and import that certificate into the keystore.  

I have generated the keystore, the truststore imported the certificates, and when I restart the NiFi Registry service the logs show no errors so I am not sure what I am doing wrong.

Below are some sanitized outputs of some commands I've ran to show what I could potentially have done wrong.

Curl Output:
