Issue Summary

On Confluence Cloud, you can share a page using a tiny link that gets created automatically when hitting Share > Copy link. That tiny link will have the following structure <site-name>.atlassian.net/l/cp/<id>.

If a licensed user tries to access Confluence through that tiny link while logged out, they will see a 'We couldn't find what you're looking for' message, instead of the login pop-up, if the instance has Anonymous Access enabled even though the space where that page is located does not have permissions to anonymous users. 

Steps to Reproduce

1. Create a Confluence Cloud page and publish it
2. Hit Share > Copy link to get the tiny link created
3. Ask for a licensed user to access Confluence through that tiny link while logged out

Expected Results

The login pop-up should be prompt since the space does not allow anonymous users to view it. The tiny link would redirect to another link (id.atlassian...).

Actual Results

The login pop-up isn't prompt even though the space does not allow anonymous users to view it. Instead, the user will 'We couldn't find what you're looking for' message, instead of the login pop-up. The tiny link gets redirected to another link instead of the URL that would allow the user to log in.

Workaround

Currently, the workaround would be disabling the Anonymous Access in the Global Permissions page.
