I want to thanks @Benjamin_Fadina. He is a great man.
I solved this problem with Benjamin's following tutorial.
This is a very interesting detail but it's worked for me.
When Benjamin has been creating a website he used an IP address (select a default one) instead of a domain name. But I was using a domain name.
Why Radzen manual deploy is not working with a domain name? who cares? It's working now.
Thank you Benjamin one more time.
UPDATE
After Benjamin's tutorial, I checked out my configuration. Domain name problem comes from one of Cloudflare's free domain redirect service. My domains are forwarding to HTTPS directly. It seems a problem in this case. But can solve easily.
So this case closed.
