[Help] Changed Hetzner IP & Google Auth stopped working

[Alaash97]

Hello , i recently changed the ip address of my Hetzner Server , but this broke google provider login in my next auth.

the domain is not changed , so i dont know how this would break the callbacks. all env variables are correct .

here more info about the error:
