I am following this example:

Calling a Web API in a daemon app or long-running process: https://github.com/Azure-Samples/active-directory-dotnet-daemon

to config auth. While after I deploy service to Azure. It start raise error like this:

Error:  System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

  • I change https to http, and it works. This is unsafe to send a request with access token. So strange. – Sui Xudong Sep 13 '18 at 07:31
