Path to UNA means path to UNA in query string, for example

• if UNA is installed at "https://example.com/" then the path would be "/"
• if UNA is installed at "https://example.com/my/app/" then the path would be "/my/app/" 

Please replace the following in you nginx config

    location / {
      index index.html index.htm index.php;
 
      rewrite "^/var/www/tavrn.social/page/(.*)$" /var/www/tavrn.social//page.php?i=$1 last;
      rewrite "^/var/www/tavrn.social/m/(.*)$" /var/www/tavrn.social/modules/index.php?r=$1 last;
      rewrite "^/var/www/tavrn.social/s/([a-zA-Z0-9_]+)/([a-zA-Z0-9\.]+)" /var/www/tavrn.social/storage.php?o=$1&f=$2 last;
 
      if (!-e $request_filename ) {
        rewrite ^/var/www/tavrn.social/(.+)$ /var/www/tavrn.social/r.php?_q=$1 last;
        break;
      }
     }
 
    # deny access to hidden files
    location ~ /var/www/tavrn.social/(\.ht|\.git) {
      deny all;
    }
 
    # deny access to specific folders
    location ~ ^/var/www/tavrn.social/(cache/|storage/|logs/|plugins/|tmp/) {
      deny all;
    }

with the following

    location / {
      index index.html index.htm index.php;
 
      rewrite "^/page/(.*)$" /page.php?i=$1 last;
      rewrite "^/m/(.*)$" /modules/index.php?r=$1 last;
      rewrite "^/s/([a-zA-Z0-9_]+)/([a-zA-Z0-9\.]+)" /storage.php?o=$1&f=$2 last;
 
      if (!-e $request_filename) {
        rewrite ^/(.+)$ /r.php?_q=$1 last;
        break;
      }
     }
 
    # deny access to hidden files
    location ~ /(\.ht|\.git) {
      deny all;
    }
 
    # deny access to specific folders
    location ~ ^/(cache/|storage/|logs/|plugins/|tmp/) {
      deny all;
    }
