Issue Summary

When clicking the App Switcher in Confluence (Application Navigator), the links don't come up and we receive an error message instead.

Environment

• Confluence 6.13+

Steps to Reproduce

1. Install Confluence 6.13.0 or later;
2. Go to Administration > Application Navigator;
3. Add a new link;
   • If you have an Application Link configured (e.g. Jira), it will automatically add a new line.
   • If there's no Application Link, anything works, like Name: "Google" - URL: "https://google.com";
4. Reload the page and click the App switcher (top right corner) button to confirm it's working;
5. Log out and click the App switcher again.

Expected Results

The links appear just fine.

Actual Results

The popup only shows "Something went wrong, please try again."

Nothing appears in the application logs, but browser network console reveals a 401 response if we click the "Try again" link:

Request URL: http://localhost:8090/confluence/rest/menu/latest/appswitcher?_=1557241377796
Request Method: GET
Status Code: 401 

Workaround

Enabling Anonymous access in Global Permissions is a possible workaround, since this is caused by an unauthorized request. As long as the spaces don't allow Anonymous access, no content will be visible.
