Thank you for your answer @sergior

The issue is the same as the one described here: [Impossible to access to production environment / Forest Admin Rails](https://community.forestadmin.com/t/impossible-to-access-to-production-environment-forest-admin-rails/1998/1)

We are working on a fix in forest-rails, we will keep you updated when the fix will be released.

In the meantime, as you shared a screenshot with a valid token on your install (I forgot to mention to blur the content), can you change the value of the `FOREST_AUTH_SECRET` on your install? It will invalidate all tokens and use a different secret for signing authentication tokens. Any random string should work here.
