Can't log in first time

First time installing on my server. Cloudways database. I get:

Unauthenticated.
vendor/laravel/framework/src/Illuminate/Auth/Middleware/Authenticate.php#95
Illuminate\Auth\AuthenticationException
*/
protected function unauthenticated($request, array $guards)
{
throw new AuthenticationException(
'Unauthenticated.', $guards, $this->redirectTo($request)
);
}

I am 100% sure I'm logging in with the same and correct name and pass I registered.
I deleted cookies and cache.

I get this when trying to log in for the first time. Database was created successfully.
