Symptoms

The following appears in the atlassian-jira.log:

2012-07-09 16:56:03,629 http-8080-3 WARN xxxx 1015x396x1 vj5zf 172.18.127.12,0:0:0:0:0:0:0:1 /rest/plugins/1.0/available/featured [upm.rest.async.AsynchronousTaskManager] Configured application base URL (https://xxx.xxx.xxx.xxx:334/jira) does not match base URL from request (https://xxx.xxx.xxx.xxx:443/jira)

Diagnosis

If your app base URL is HTTPS and doesn't explicitly specify a port, UPM wrongly displays a base URL mismatch warning because it thinks the port is supposed to be 334 instead of 443. This does not disrupt any UPM functionality, it just causes a misleading warning banner to appear all the time at the top of the UPM page.

Cause

This is caused by a bug in UPM 2.4. Please see UPM-2339 for more info.

Resolution

Upgrade to UPM 2.4.1. Please see Upgrading the Upgrading Universal Plugin Manager for more info.
