Getting 403 error

As the title said itself, I'm getting 403 in non-local environment. I already added

canAccessFilament()

canAccessFilament()

in my user model, but I slightly modify it so that it can accommodate filament shield.

public function canAccessFilament(): bool
    {
        return $this->hasAnyRole($this->roles);
    }

public function canAccessFilament(): bool
    {
        return $this->hasAnyRole($this->roles);
    }

What went wrong?
