CORS block only localhost request - express

Question

I have a problem with my server developed in EXPRESS and hosted on NGINX.
I use passport.js for user authentication, even if I don't think this is the problem, and when I try to login from localhost I get an error while if I run it by uploading it to my domain I don't get it wrong and it works correctly, so I think it's a CORS problem blocking localhost requests.
NGINX default
server {
root /var/www/html;
index index.html index.htm index.nginx-debian.html;
server_name api.mysite.com www.api.mysite.com;
location / {
proxy_pass https://localhost:3007; #whatever port your app runs on
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
if ($http_origin ~* (^https?://([^/]+\.)*(mysite)\.com$)) {
set $cors "true";
}
if ($http_origin ~* (^http?://([^/]+\.)*(localhost:3006))) {
set $cors "true";
}
if ($http_origin ~* (^https?://([^/]+\.)*(192.168.1.21:3006))) {
set $cors "true";
}

Answer 1

If anyone else had this problem I solved it by configuring the 'express-session' in this way
var session = require('express-session');
const sessionParser = session({
secret: 'your-secret',
resave: false,
saveUninitialized: true,
cookie: {
secure: true,
httpOnly: true,
sameSite: 'none',
maxAge: 1000 * 60 * 60 * 12 // milliseconds * seconds * minutes * hours
}
})
