Trouble accessing JIRA Marketplace

[Deleted user]

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?

As a follow up on this, I performed an in-place upgrade from 8.0.2 to 8.1.0.  Without deleting the keystore or modifying any existing configuration files, the Marketplace is now connecting and appears to be working. 

The upgrade did overwrite my cacerts file, but I manually made a backup of my files before the upgrade and the replaced 8.1.0 CACerts with my 8.0.2 file.  Other than that, all the other configurations remained.

Not sure what changed, but it may have been a bug in 8.0.2; or something didn't get installed properly and the upgraded corrected it.  Not sure, but at least it's working.

Is your application behid a proxy? If so you need to configure your network proxy using JVM variables.

No, it's not behind a proxy.   Our firewalls or content filters are not blocking it.  I can pull up the Marketplace website up via lynx from the cli of the server.
