Repro

1. Install all the dependencies (I use pnpm)
2. Run the server in dev or preview mode and navigate to http://localhost:3000/protected
3. You should get redirected to /auth/login and have the option to log in (take a look at the client & serverside logs)
4. Stop your dev server
5. Build the site with pnpm build
6. Run the server through the adapter via node _build
7. If you are logged in, you'll get thrown to the login page event though you have a token cookie set
8. In any case, you won't be able to log in anymore
