While requesting to HCP server (PUT file) i got error "ErrorMessage: The SSL connection could not be established, see inner exception" with description "Authentication failed because the remote party sent a TLS alert: 'HandshakeFailure'"

It's everything ok when i try it using postman:

I created console app to test it (8.0) and try few methods:

RestSharp:

var options = new RestClientOptions("https://...")
{
    MaxTimeout = -1,
    FollowRedirects = false,

};
var client = new RestClient(options);
var request = new RestRequest($"...", Method.Put);
request.AddHeader("Authorization", "...");
request.AddHeader("Content-Type", "application/pdf");
request.AddParameter("application/pdf", attachment, ParameterType.RequestBody);
RestResponse response = await client.ExecuteAsync(request);

HttpRequestMessage:

var client3 = new HttpClient();
var request3 = new HttpRequestMessage(HttpMethod.Put, "...");
request3.Headers.Add("Authorization", "...");
request3.Content = new StreamContent(File.OpenRead("..."));
var response3 = await client3.SendAsync(request3);
response3.EnsureSuccessStatusCode();
var response3Content = await response3.Content.ReadAsStringAsync();

HttpWebRequest:

HttpWebRequest request2 = (HttpWebRequest)WebRequest.Create(url);
request2.Method = WebRequestMethods.Http.Put;
request2.AllowWriteStreamBuffering = false;
request2.SendChunked = true;

request2.AllowAutoRedirect = false;
request2.Headers.Add("Authorization", "...");
using (Stream dataStream = request2.GetRequestStream())
{
    using (MemoryStream fileStreamToRead = new MemoryStream(attachment))
    {
        fileStreamToRead.CopyTo(dataStream);
    }
}
var response2 = (HttpWebResponse)request2.GetResponse();

I get this error every time. I try to set:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls13;

And

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

But any of them dont help. Only in combination Tls13 and HttpWebRequest i got another error:

The client and server cannot communicate, because they do not possess a common algorithm

How to resolve the problem and what postman doing background what fix it?
