The problem is the HN post links to https://sleekui.com/ https://sleekui.com/ which immediately redirects to https://sleekui.com/category/design https://sleekui.com/category/design - when you hit the back button, it tries to go back to the homepage but then is redirected again. So it's not possible to get back to HN using the back button after clicking into your site. One easy fix is to edit the HN submission link (if it lets you) to link to /category/design instead of the homepage.
