Bot Framework Emulator: Unknown Host

I'm developing a simple Dispatch Bot, I only have a basic structure now to chose between QnA or LUIS models but when I test it in the Bot Framework Emulator, the AdapterWithErrorHandler catches and error and i get no response from LUIS neither QnA.

everytime i send a message.

I checked the appsettings.json and everything seems to be fine. I want to point out when I created the LUIS App a default key was given to me, and later on i linked it with the Cognitive Resource i have in Azure and a second key was given. Which one do I need to use?

I got everything hosted in the West Europe server except the QnAMaker resource (which I haven't read anywhere this should cause any problem).

This is the Emulator Log window, as you can see the problem doesn't occur until I send a message. It looks like it connects properly but then can't find the hosts. The message displayed is from the Adapter that catches de exception.

Update: that might be relevant to the problem, whenever I try to open my csproj file to see its contents this message is displayed:

catastrophic error hresult 0x8000ffff (e_unexpected))

I am not sure about the error you encountered and I have not met this error on my side.

But I run NLP DispatchBot sample on my side successfully , with the steps below , maybe will helpful for you :

1. I created a LUIS app and a QnA maker for demo, if I query "help" to my LUIS , it will reply "Help" intent, it is deployed on westus:

and this is the party content of my QnA maker :

2. Mapping appsettings.json file in project : LuisAPIHostName in your case should be westeurope

   3. In my case , if I type help, LUIS will reply "Help" intent so that direct to QnA service, so I modify the matching value in DispatchBot.cs file under DispatchToTopIntentAsync to make sure "Help" intent can be matched to lead me to QnA service :

   4. Test on local:

If you have anything unclear , pls feel free to let me know.
