What is your current Discourse version?

There was a similar bug report recently which was fixed

A loading loop will occur when user try to fetch the former/latter page of a removed topic

For these steps: Login as a user, and read a topic; The admin/moderator removes the topic; Go up/down and trigger the fetch of the former/latter page. Then the page will stuck in an infinite loading, with the console showing 403 forbidden getting /t/${this.topic.id}/posts.json. And if the website is protected by a waf, then the user will be banned from visiting it.
