• The issue happens when the token is expired by a bug on the application, so we can't trigger it
• The token gets expired and Confluence reach for an invalid information on the cache of our media servers

Expected Results

• Images should be displayed to the user

Actual Results

• Images are missing, just a placeholder of it is displayed.
