Next Auth does not work in production

[thick crescent]

I have an application that uses next auth and it works perfectly in development, but in production when I try to log in, I receive the following error: https://my.domain.here/api/auth/error?error=fetch%20failed

I have another application that uses EXACTLY the same configuration and works perfectly in development and production, can anyone help me understand what is happening?
