Frontend is not receiving auth cookie from server after deployment

Hi support team.
I have deployed my react app on netlify, and my api backend on azure app service (.net core).
I use jwt authentication and store into cookie. In my backend code i use Response.Cookie.Append() to append the auth cookie to browser. which work fine in development

but when deployed it’s not append the cookie.
You can check my site here Front-Deployed.
I have look into similar post but none fix it. similar

Hi @KyNguyen,

As far as I can see, the cookie is not being sent to the browser:

This is not a Netlify issue and it’s your backend that’s handling the cookie, Netlify is not involved in that process.
