Jira is unable to communicate with itself via its Base URL

Question

We checked firewall arrangements, everything seems as it should.  Jira application refuse to connection, how could we find reason ?

Is there a arrangement on the Jira app side that needs to be changed to enable this communication?

Curl:(7) Failed to connect couldn't connect to our base url port: 443 Connection refused

I would re-check the firewall - connection refused is a typical response from a firewall block.
