This issue occurs if the customer enables a Wifi adapter and allows connection from internet via TeamViewer. If the Wifi adapter is disabled the connection works well. An already connected gRPC client (which is opened before the Wifi adapter is enabled and connected to internet) hold the connection successfully. A newly created connection fails, but again with grpcurl.exe it works fine. We already checked firewall on/off; IP adapter settings (only enable IP4 feature) We are wondering that tnc tool and grpcurl.exe can connect but the dotnet test client cannot.

HttpClient is (or was?) very reluctant to talk non-TLS HTTP2; this might only apply to .NET Core 3.x and might be outdated, but: we can at least try...

can we try twisting it's arm? Add (early on, in the client code):

AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);

(if this is the cause, then I'm going to recommend that we detect this scenario and throw a bespoke exception that tells the user what to do, so: please don't close this if this works)

mgravell commented 1 year ago

Looking at this locally, I do not think the app-context flag still applies - I'll stop mentioning that. My apologies for the confusion.

Right; next things... what protocols is the server binding to? Without TLS, you cannot use Http1AndHttp2 (it should be Http2) - although setting this up locally to investigate, I get a slightly different stack trace - it fails (as expected), but it fails differently:

Is there a runnable repro I can look at here?

Related to https://github.com/grpc/grpc-dotnet/issues/2190#issuecomment-1642204763 I added AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true); at the first line in source code (mentioned above), but as you presumed there is no change. The log-files looks exactly like above mentioned.

  1. Originally the server and client are written in Grpc.Core. Even the Grpc.Core client falis to connect the server. After that we wrote the test client with the current Grpc.Net library, because Grpc.Core is obsolete. The server still runs under Grpc.Core and I did not found a similar setting like Http1AndHttp2.
  2. We made a test with a second PC in the same network and WiFi adapter connected to internet. However at this PC the test client finish successfully:

So it depends on dotnet and/or that specific customer PC.

The dotnet runtime of the customer PC is:
