Bot Emulator gets POST 500 directline.postActivity

Question

I am trying to connect Microsoft Bot Emulator to my bot. Everything works fine when I host my bot locally but I hosted my bot at the following URL

https://hospitalbot.azurewebsites.net/api/messages

When I connect my bot using the Emulator and send a message it says the following (the log below)

[16:05:17]Emulator listening on http://localhost:51103

Before you connect to a bot that is hosted remotely, please make sure you installed and configured ngrok tunneling software.
