Hey 😃 I deployed my app on another server using the same FOREST\_AUTH\_SECRET and FOREST\_ENV\_SECRET that I had in production and then I simply changed the url in forest-\>project setting-\>environments but it turns out that it doesn’t let me login, when I try to log in it tells me Unable to authenticate you. Where am I going wrong? isn’t that how you change the url? thanks for any help ---

Hey @usr1vang, Did you also update your `APPLICATION_URL` environment variable ? Could you also remind me this project name & version of `forest-express-*` you are using ? ---
