Authentication lost after proxy_pass

I am trying to setup multiple SPA (Angular) behind NGINX proxy_pass. Of which on is a simple front-facing app which behaves more as a landing page for the other apps. I’m able to login as expected from that landing site but when navigating to one of the apps (proxy_pass) all authentication is lost. Even when I navigate back I have to login-in again.

What would be an expected setup to allow authentication to persist between multiple SPA provided via proxy_pass?

Turns out that the NGINX was setup correctly and not the problem. The root was simply incompatible version of the @auth0/auth0-angular libraries. Once all the “apps” used the same version things are working as expected.
