Problem with connection. Failed to establish SSL connection with the HTTP server

[xerasy]

request.UserAgent = useragent;
request.IgnoreProtocolErrors = true;
request.SslCertificateValidatorCallback += (sender, certificate, chain, sslPolicyErrors) => true;

var result = request.Get("https://sscasino.online/");

but i get error
Failed to establish SSL connection with the HTTP server

i get the same the error for WebRequest

  WebRequest req = WebRequest.Create(Url);
  WebResponse resp = req.GetResponse();
  Stream stream = resp.GetResponseStream();
  StreamReader sr = new StreamReader(stream);
  string Out = sr.ReadToEnd();
  sr.Close();

but solution for WebRequest is a add line
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

what is the solution for xnet ?

Looks like its a SslStream issue.
Put in on HttpRequests.cs on line ~2595
sslStream.AuthenticateAsClient(address.Host, null, SslProtocols.Tls12, false);

instead default line
sslStream.AuthenticateAsClient(...)

Yes! you must set "request.SslCertificateValidatorCallback += delegate" return true

[angelocart]

Replacing the line sslStream.AuthenticateAsClient(...) with sslStream.AuthenticateAsClient(address.Host, null, SslProtocols.Tls12, false); returns an error of "SslProtocols' does not contain a definition for 'Tls12'.

Please fix, thanks!

This repository no more supported. Try this one:
https://github.com/Fedorus/xNetStandard

Its for .netStandart. Lost all operations connected with winAPI plus GZip connections (some error with GZipStream in .net Core).

Thank you for the response! I will let you know if any other errors occur.

Does the previous documentation for xNet apply to the new repository?

There was no breakink changes in API, but there may be bugs in fixes that I`ve described above

Okay. Thank you again for the quick reply.

@Fedorus I use Visual Studio 2015. I cannot open the project files for xNetStandart so I cannot build the DLL file. Could you build the DLL and upload it?

sslStream.AuthenticateAsClient(address.Host, null, (SslProtocols)3072, true);
