• what is trying to create

Answer 1

I agree with the main Answer by Shaun Luttin but also,

In my case: after the deployment i take this error and i found the reason is using the Hsts Preload after inserting SSL certificate. Uncommenting this lines solved the redirection, and it solved this error completely

 //app.UseHsts(options => options.MaxAge(days: 18 * 7).IncludeSubdomains().Preload());
