On Confluence Server, Custom Charts will automatically link to the Primary Jira connected to the Confluence instance.
Only the Primary Jira will be used and it is currently not possible to select an alternative if multiple Jira instances are connected to Confluence. If you require this additional functionality please contact our support team to discuss this feature.
Custom Jira Charts for Confluence Server & Data Center can only be used with Jira Server & Data Center instances.
Jira must be connected to Confluence using OAuth (impersonation) and the usernames must match exactly on both instances for Custom Charts to function as expected.
A detailed description (with screenshots) of how to correctly configure the application links can be found here: Server - Application Link Set Up
