Question

It seems that if you deploy your bot to the cloud and try to test it from the emulator it will give this error. The emulator seemed to work in 2 cases:

1- Localhost with security disabled (remove appid and app password)

2- localhost with security enabled (add appid and app password)

both endpoints via http only because it's localhost. If you deploy to the cloud you can test it in the emulator available on the Bot Portal. Make sure the endpoint for the hosted bot is https enabled.

I followed the steps in this troubleshoot guide and it fixed it for me: https://docs.microsoft.com/en-us/bot-framework/troubleshoot-authentication-problems

I didn't understand what actually caused the problem though. What I noticed was: desktop emulator works with localhost only.
