Try to upgrade your client version to the latest version and also check Elasticsearch Nest official issue thread:

We tried following thing to fix this issue but not succeed.
We have reset connection time out - 30 second and connection limit to 500.
Changed elastic search api port no 9800 to 9801.
We haver changed public IP address to private IP address.
I am getting Unauthorized error, bot setup details are given below. I have tried the same setup in commercial azure and it's working. Issue is only in GCC High Azure.
bot Setup in Azure portal (portal.azure.us)
Created Azure Bot in Azure portal.
Add new client secret in Bot Azure App.
Added redirect URI in authentication settings "https://tokengcch.botframework.azure.us/.auth/web/redirect"

Has anybody got a clue why this exception is being thrown or what it even means? I really appreciate any help you can provide.
My chatbot uses QnAMaker to respond to questions from the user. Recently this has stopped working when I'm testing in the Bot Framework Emulator. The bot is functioning perfectly in Web Chat however. I believe the issue occurs when I try to generate an answer from my QnAMaker Knowledge Base:
var response = await botServices.QnAServices[QnAMakerName].GetAnswersAsync(stepContext.Context, qnaMakerOptions);
This is the output I am getting in the console:

Testing in the emulator always worked fine up until now. Anyone know how to solve?
One item that can cause this is if your development configuration is different from your Azure configuration. Please compare your QnAEndpointHostName, QnAEndpointKey, and QnAKnowledgebaseId to see if they differ between local and Azure.
If you've done anything different with local config lately, verify where those credentials are coming from. e.g. ASP.NET appSettings, secrets manager, or environment.
Also, since some of the stack trace is working with SSL types, you might want to double check that you're QnAEndpointHostName has an https protocol prefix.
After updating to the latest version of visual studio 2015, I am unable to use the XAML designer due to the fact that each time I attempt to open it a screen appears to inform me that a NullReferenceException has occurred.
I have tried the solution detailed in the post below, However, as I am not a HP user this solution didn't work for me.

Please see the attached screenshot and error message below. Any help would be greatly appreciated

You will have some code in a constructor that relies on something that would normally be set only at runtime (a database connection for example).
You will need to wrap the code in a test like this:
if (!Windows.ApplicationModel.DesignMode.DesignModeEnabled)
{
// Runtime mode specific functionality
}
Note The DesignModeEnabled property is available only in the presence of a developer certificate.
Source
You can either do this for all the code in the constructor or try to narrow it down so you only have the test round the minimum possible code. Alternatively you should look at moving that code out of the constructor into an OnLoaded event handler.
The same thing happened to me. I deleted the .vs, bin, obj directories in the project and it worked.
