You don't have permission to view this page when linking a Confluence page to a JIRA applications issue
When you have an application link between a JIRA application and Confluence page, the page is linked yet the message "You do not have permission to view this page" is displayed. If you click on the page, you will be able to access it just fine.
The main known causes to this problem are:
- Remote API (XML-RPC & SOAP) features in Confluence are disabled
- If a Trusted Application link is being used to connect JIRA and Confluence:
- The Outgoing "IP Patterns" and/or "Remote Addresses" boxes are not configured correctly.
- Certificate timeout error.
For Cause #1
Follow the Enabling the Remote API documentation to adjust that setting on Confluence.
For Cause #2
Optional: Switch to an OAuth application link between JIRA application and Confluence, rather than Trusted Applications. OAuth will not need the below settings. See How to adjust an existing Application Link to use OAuth for instructions.
Under the Problems caused by incorrect URL filters heading, and ensure you have at least the below URLs allowed in the incoming section for Confluence end of the link.
/rpc/xmlrpc /plugins/servlet/applinks/whoami /plugins/servlet/streams
Set certificate timeout value to zero if any certificate error/warning message occurs in the logs,
