Issue observed since Jira9.0. Fixed versions:

✅ stable/9.4.x
✅ stable/9.12.x
✅ stable/9.15.x
✅ stable/9.16.x
✅ master

A Confluence page with an Advanced Roadmaps Plan macro shows a baseURL warning popup every time you visit the page.

This is reproducible on Data Center: yes

Environment

Tested with:

Even though everything is in order in the server.xml, pop-up warns about there is a misconfiguration in server.xml with a strange suggestion for proxyName: confluence.bbeykoz.lanhttps

This time it gives a warning about reaching the gadget from the wrong baseURL. You can see that it is mentioning Jira baseURL although the gadget is added to a Confluence page.

Steps to Reproduce

1. Install Jira + Advanced Roadmaps for the Jira app
2. Install Confluence + Advanced Roadmaps for Jira in the Confluence app
3. Create a reciprocal application link between Jira and Confluence
4. Create a plan using Advanced Roadmaps for Jira on the Jira side
5. After creating the plan, click "Share"
6. Select Confluence from the opened panel, click the "Generate link" and copy the URL.
7. Create a page on Confluence
8. Add Advanced Roadmaps Plan macro and use the generated URL from the previous step
9. Publish the page

Expected Results

The Advanced roadmap macro should be displayed without any pop-ups or warnings.

Actual Results

You will see a baseURL warning popup when the page loads. Based on your network topology, the message can differ.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
