And here is the Nginx config

nginx config

server {
listen 80;
server_name candy-cases.com www.candy-cases.com;
access_log /var/log/access.log;
error_log /var/log/error.log;
rewrite_log on;
root /var/www/candy-cases.com/public;
index index.php index.html;
location / {
  index index.php;
  try_files $uri $uri/ /index.php?$query_string;
  #expires -1;
        #add_header Pragma "no-cache";
        #add_header Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0";
        #try_files $uri $uri/ /index.html ;
   	#rewrite ^(.*)$ /index.html;
}

if (!-d $request_filename) {
  rewrite ^/(.+)/$ /$1 permanent;
}

location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}

location /api {
    index index.php;
    try_files $uri $uri/ /index.php?$query_string;
}

location ~* \.(?:ico|css|js|jpe?g|JPG|png|svg|woff)$ {
expires 365d;
}


}

But the problem is that my config seems to handle requests with '/api' just fine, but simple '/' doesn't.
If I try to access something other than '/api', it just redirects to the root of the site.
