You could try the fix that was proposed here:

This basically changes the way that nginx (nginx_internal.conf) switches between Backend and Frontend depending on the content type specified in the request.

PR #3249 got reviewed, approved and then merged by Nutomic and then reverted by dessalines because …

Also, when you set Type to Subscribed in Settings the front page default feed only contains posts from communities you have actually subscribed to.

This does not prevent lemmy.world from accidently hosting illegal content, but it helps to protect your own feed from unwanted stuff.
