Problem

Team Calendars that it doesn't show a Login link when the oAuth credentials to Jira are no longer valid.

Environment

Applications: Confluence 10.2.13 with Jira 11.3.8
Application Link: Connected as oAuth 1.0

Steps to Reproduce

1. Created a new Team Calendar onto a Confluence page and added Jira Sprint event to the Calendar
   1. Results appeared correctly in Confluence Team Cal
2. Purposely then broke the application link on Confluence side
   1. Navigate to Confluence Administration » General Configuration » Application Links
      1. Disabled outgoing on the App Link
   2. Navigate to Confluence Administration » General Configuration » Cache Management
      1. Clicked Flush All
   3. Navigate to Confluence Administration » General Configuration » Application Links
      1. Enabled the outgoing on the App Link back to oAuth
3. Reloaded the Confluence page with TeamExpected Results

Calendar should show without errors

Workaround

Add the Jira Issues Macro to a Confluence page

1. Open any existing Confluence page and click Edit, or create a new blank page.
2. Click somewhere in the page content area where you want to add the macro.
3. Type: /Jira
4. From the list of suggested macros, select Jira Issues.
5. If prompted, click Login & Approve to refresh the Jira connection and authorize Confluence.
6. Complete the macro setup, or close the configuration window if you only need to refresh the connection.
7. Click Publish or Update to save the page.
8. Refresh the affected Confluence page and check whether the error has been resolved.
