Why are cookies not saved on the client after deployment?

Question

Node.js

Please tell me, there is authorization on the site, after a successful login, cookies with a token are saved on the client, everything worked on the localhost, the cookies were saved, but after the deployment, the authorization is successful, but the cookies are not saved on the client.

import * as cookieParser from "cookie-parser";
app.use(cookieParser());
  app.enableCors({ origin: "url сайта", credentials: true });

There is a cookie parser, everything is fine with the cors.

response.cookie("token", token, { httpOnly: true });

this way I save cookies on the client.
Cookies are not saved only after deployment, what should I do?

Answer 1

The domain is probably not the same. Look in the HTTP headers for specific cookies.
Still there is a variant that lifetime is incorrectly specified.
