Theme CSS Only Viewable From HTTP not HTTPS

UPDATE: The CSS is now viewable on the site but only on the HTTP version (not the HTTPS). I made this happen by disabling the redirect from port 80 to port 443.

My website is running on OS X Server v5.0.3. WordPress is stored in a subdirectory of the root website (Site/wordpress/). I am able to view and interact with the site with full formatting if I navigate to it on the local machine (localhost/wordpress/). However, when attempting to access the site on the internet using my domain name (https://gaba.space/wordpress) I am greeted by a page without the formatting of any theme I try to apply to the site. I have tried multiple themes and none have made a difference to this issue. I have also checked the permissions of the theme directories to make sure they are readable by any user. This issue is not urgent but any insight you may have into the situation would be greatly appreciated.
