Issue/Introduction
Upgraded Linux from RHE7 to RHEL 8 and then swapped the IP and Hostname. After enabling HTTPS on the server and attempting to integrate with Spectrum, the collector would not integrate and there were no outstanding errors in the OneClick Tomcat log other than Spectrum just indefinitely waiting for the VNA response.
Cause
Created the cert on the new server with FQDN where SAN is needed to include Hostname, FQDN, IP, and the servers NATed IP.
Resolution
You can manually recreate the SSL certificate including all the SAN names.
On the VNA system
Stop Wildfly: systemctl stop wildfly
Rename the current keystore.jks file (we will generate a new one)
