Symptoms
When in the plugins area of JIRA, you get a warning that you are not able to connect to the UPM
The following appears in the atlassian-jira.log:

The automatic checking for updated plugins will not function correctly, but you will still be able to find and download plugins from the UPM despite the error message.
This will prove true only if there are no other proxy or firewall connections creating an issue.
