Error - Request was aborted: Failed to create SSL/TLS c# secure channel?

Question

C++ / C#

Hi all. Tell me, please, what to do. I want to programmatically (C#) download a sitemap from https://www.ralphlauren.com/sitemap_0.xml, but I get an error.

xml = client.DownloadString("https://www.ralphlauren.com/sitemap_0.xml");

Exception thrown: 'System.Net.WebException' in System.dll ("Запрос был прерван: Не удалось создать защищенный канал SSL/TLS.")

I registered in php in curle and everything works like clockwork, but how can I do it in C # or what should I do?
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
