JIRA Issue Macro in the Confluence page is using Display URL while the Application URL is unreachable.
1.Link Jira server and confluence cloud.
2.Ensure that the Display URL and the Base URL of Confluence and JIRA is using the proxied URL.
3.Create a page in Confluence and insert a JIRA Issue Macro.
The JIRA macro issue links should redirecting to Display URL: https://helpdesk-vn.xyz.com\ (this is Jira server URL)
If we access the single issue link then it works fine.
