Hi,

I'm trying to do a https-request agains my server like this:But i received this Exception:

var result = new WebClient().DownloadString("https://myserver.com/securedata");

Runtime Error: Error: SecureChannelFailure (The authentication or decryption has failed.) The authentication or decryption has failed. Error while sending TLS Alert (Fatal:InternalError): System.IO.IOException: The authentication or decryption has failed. ---> Mono.Security.Protocol.Tls.TlsException: The authentication or decryption has failed. at Mono.Security.Protocol.Tls.RecordProtocol.EndReceiveRecord (System.IAsyncResult asyncResult) [0x00040] in <e220be0b0a364427860ee43376ab6f2b>:0 at Mono.Security.Protocol.Tls.SslClientStream.SafeEndReceiveRecord (System.IAsyncResult ar, System.Boolean ignoreEmpty) [0x00000] in <e220be0b0a364427860ee43376ab6f2b>:0 at Mono.Security.Protocol.Tls.SslClientStream.NegotiateAsyncWorker (System.IAsyncResult result) [0x00071] in <e220be0b0a364427860ee43376ab6f2b>:0

I added this ServerCertificateValidationCallback - but it fails with the same error!

System.Net.ServicePointManager.ServerCertificateValidationCallback += (o, certificate, chain, errors) => true;

Can you help me and tell me how to do a https request?

Thanks!

Hi Michael. In the cloud, we are pinned at Mono 4.6.15 at the moment. This was the last version of Mono without memory leaks that has allowed the community's algorithms to run without issues for 6+ months. Unfortunately, this version of Mono has this HTTPS bug...

You will need to serve it as HTTP unfortunately. If you cannot do this then I'll see about QuantConnect hosting an HTTPS->HTTP wrapper endpoint until the Mono version is upgraded.

Ok, I'll try to serve my data as HTTP.

Thanks for your answer.
