Hey! I feel you—the 403 forbidden nginx proxy manager error is super annoying. One thing that worked for me was disabling directory listing in the Nginx config. Add `autoindex off;` to your server block if it’s not there already.
Also, check if your firewall (like UFW) is blocking traffic. Sometimes it’s not Nginx but something else in the stack causing the issue.
