I have deployed a Laravel app using forge and I'm running nova on a subdomain. When I try to login with correct email/password combination, nova requests https://my.sub.domain/dashboards/main but fails with a 409 error, then reloads the login page.
When I enter an incorrect email/password combination, the auth.failed message is displayed as expected. Whether or not an email address is entered in the Nova guard array does not make a difference. On my local installation everything works fine.
Please let me know if you have any idea on how to debug this!
