Sometimes "Couldn't read the packet length" under Linux (.Net Core) #1013

Open mightywill opened 3 years ago

mightywill commented 3 years ago

When I try to send message from Kestrel webserver under Linux that was some time in idle state(no requests) then a first two attempts fail with "Couldn't read the packet length" or "Broken pipe" but the 3rd and the following succeed

Couldn't read the packet length

Can reproduce on Windows 10 19042.746 with .NET Core 5.0.102 and TLSharp version 0.1.0.574 (NuGet). Happens frequently on multiple methods. (threw on ConnectAsync and SendCodeRequestAsync)

EDIT: I assume this is due to .NET Core and .NET Framework incompatibilities

Hi @novelhawk, @mightywill Same error I got on Windows Server 2016 with ASP.NET MVC app I'm using .NET framework 4.7.2, and TLSharp version 0.1.0.574 (NuGet) Mostly message sent, but sometime I got the following error

Couldn't read the packet length

It seems that there are known incompatibilities in using this library in core environment. (See #687 #893 #763)
