Found the issue.
My environment is set to accept multiple domains and the server had domain A set as default whereas ModX had domain B as default. As a result, whenever I tried to preview an unpublished page, ModX didn't recognize me as an authenticated user and thus redirect me to the 404 page.
I have also same problem.
