plesk-nginx-extra-reverse-proxy.conf

## If someone enters two slashes, '//' combine them into one
merge_slashes on;
 
## Make sure everything is forwarded to https://
if ($scheme = http) {
    return 301 http://$server_name$request_uri;
}
 
## Remove trailing slashes
rewrite ^/(.*)/$ /$1 permanent;
 
## If the index.html (can be anything) is looked for, redirect to /
## Fix for Plesk location /{} forcing index.html to be loaded
rewrite ^(.+)/index.html$ $1 permanent;
 
location = /index.html {
    internal;
    error_page 404 =301 $scheme://domain.com/;
}
 
## If the location is equal to /
location = / {
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_pass http://127.0.0.1:3000;
}
 
## Proxy pass everything else to node as well
location ~ / {
 
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_pass http://127.0.0.1:3000;
