Hi I recently bought a VPS that is fully unmanaged.
Note: I changed my domain name to "mydomainexample.com". This is the only part which I changed.
As I do not have my own SSL Certificate, after installing Phusion Passenger and deploying a Node.JS (ExpressJs) Web Application on mydomainexample.com/, I proceed to cPanel > SSL/TLS Status and clicked on 'Run AutoSSL'.
However, the domain is still not secure and upon checking the Logs in WHM > Manage AutoSSL > Logs
I saw this:
Log for the AutoSSL run for all users: Thursday, April 21, 2022 6:16:20 AM GMT+0800 (cPanel (powered by Sectigo))
6:16:20 AM AutoSSL’s configured provider is “cPanel (powered by Sectigo)”.
This AutoSSL provider does not poll for certificate availability immediately after a certificate request submission. Instead, it submits certificate requests then periodically polls the cPanel Store for each requested certificate and installs it after a successful retrieval. The system will record all requests, retrievals, and installations for the current AutoSSL run in this log.

There were 2 text highlighted red - I'm not sure what they mean:
6:16:20 AM ERROR TLS Status: Defective
ERROR Defect: OPENSSL_VERIFY: The certificate chain failed OpenSSL’s verification (0:18:DEPTH_ZERO_SELF_SIGNED_CERT).
As I'm still a beginner in setting up servers I'm not really sure what to do. Could someone point me in the right direction?
