I can reproduce: start downloading an ISO and then disconnect Wi-Fi - PowerShell hang (no response after Ctrl-C and Wi-Fi reconnect).

If there is the VPN- or proxy-program between PowerShell and Internet, that program (probably) is returning the connection error and PowerShell by itself (without external intervention) is continue after 1-2 minutes with $_.Exception.HResult -EQ -2146232800, $_.Exception.InnerException.ErrorCode -EQ 10053 and $_.Exception.InnerException.Message -Like "Unable to read data from the transport connection: *".

Even though we have StopProcessing() implemented, because we have HttpClient.SendAsync() being run synchronously.. I think it is blocking the cancellation.

PowerShell/src/Microsoft.PowerShell.Commands.Utility/commands/utility/WebCmdlet/Common/WebRequestPSCmdlet.Common.cs

Line 1358 in 7cf1ef8

response = client.SendAsync(req, HttpCompletionOption.ResponseHeadersRead, _cancelToken.Token).GetAwaiter().GetResult();
