Laravel + Nginx. Session is accessed randomly

We have an app build in laravel and we are trying to switch from apache to nginx but when we enable the nginx, the users are getting logged into random users account on every refresh.

For example,

I am logged in as USER1, refresh the page and now I am in USER2 account, USER3 account randomly.

We are using redis as session driver.

Thanks.
