The JIRA Remote API plugin fails to connect to Confluence using the XML-RPC and throws an exception.
Resolution
First stack trace: Enable the remote API in Confluence as per this KB article: Enabling the Remote API. There is an open ticket asking JIRA to switch to REST instead of XML-RPC for page retrieval: JRASERVER-61128 - JIRA should use REST API to search Confluence pages and Link Jira Issues
Second stack trace: Enable the Confluence Remote API system plugin via Manage Add-ons > System.
