Please go to the repository properties and validate the repository. If errors about circular redirects are logged in your Eclipse error log, your JIRA server or proxy may not be configured correctly.
In some cases unexpected redirects can be caused by a JIRA server accessed via Apache and mod_jk (using the AJP/1.3 Tomcat connector). Some server configurations may benefit from the ‘proxyHost’, ‘proxyPort’, ‘scheme’ and ‘secure’ settings on the AJP Connector in the Tomcat server configuration.
Please see this issue for more information.
