Universal Plugin Manager Firewall Configuration
Symptoms
Administrators are unable to use the Universal Plugin Manager because of a firewall configuration preventing downloads.
Cause
The Universal Plugin Manager makes calls to plugins.atlassian.com for metadata about the plugins installed. In order to pull down updates for the installed plugins, it contacts the various different repositories in which the plugin developers publish their plugins.
Workaround
Administrators can download plugins manually from the plugin exchange, then upload them from the JIRA server (via Administration >> Add-ons.
Resolution
As plugins.atlassian.com is a dynamic community of developers that undergoes constant improvement and change, it's very difficult to provide a static list of servers to whitelist for a static firewall. An initial configuration, to allow the plugins supported or hosted by Atlassian, is to open these repositories:
https://maven.atlassian.com https://marketplace.atlassian.comIf your firewall needs specific IPs for whitelisting, you can ping both addresses above as the IP for those URLs are not static at this point in time. You 'll want to run the following in a command prompt or terminal to get the according IPs.
ping maven.atlassian.com ping marketplace.atlassian.com
