Hi, the culprit is in the enabled TLS cipher suites list. Compared to my machine, your machine has disabled the following: TLS_AES_256_GCM_SHA384 TLS_AES_128_GCM_SHA256 These are TLS cipher suites necessary for...

I filed an issue in .NET runtime (it is linked above) to improve diagnostics, it should be easy to detect, but I first need to take a bit more time...

@ubercellogeek I have problems investigating the attached dump (cannot walk the heap). The file is rather small, is it a full memory dump? Do the subsequent reads after the 0...

In the provided dump, the `_receivedEOF` flag is set ``` 0:000> !dumpobj /d 265d9446438 Name: System.Net.Security.SslStream MethodTable: 00007ffa43c9c860 EEClass: 00007ffa43caee90 Tracked Type: false Size: 256(0x100) bytes File: C:\Program Files\dotnet\shared\Microsoft.NETCore.App\8.0.8\System.Net.Security.dll Fields:...

Do you have any other way to confirm that the data itself is actually being truncated? Another thing that can be checked out is examining the network traffic via Wireshark...

I think I see the problem. ```cs var mimeType = _streamIn?.ReadLine(); var length = Convert.ToInt32(_streamIn?.ReadLine()); var buffer = new byte[length]; var totalBytesRead = 0; var timeout = DateTime.Now.AddMilliseconds(NET_READ_TIMEOUT); while (totalBytesRead...

I think the documentation is correct, if I use your example and change the `FourPointsString` to log the following ```cs public static string FourPointsString(this Rect rect, string string_format) { StringBuilder...
