I am having trouble getting the Atlassian Marketplace configured on JIRA 8.0.2. This is a relatively new server/build; installed just before 8.1 was released. I do plan to upgrade to 8.1, but had to get some other things working/tested/configured.
JIRA is running on http port 58080. I imported the marketplace certificates into keystore. SSLPoke and httpclienttest Java tools are successfully connecting to the server. The catalina.log does not show any errors. The "Integrity Checker" shows no errors. The "Instance Health" shows no errors.
In the "JIRA -> Administration -> Applications -> Versions & licenses" is displaying "The Atlassian Marketplace server is not reachable. Available application updates will not appear on this page." For the past week, I've been troubleshooting this, but unsure of what/where to look to correct this issue. I've looked at numerous resources and articles, but no success. Any guidance or suggestions?
