Issue Description

I have V3 BOT with Microsoft teams channel. I see following sporadic issue where it seems like teams is failing send response back to bot via serviceURL

There is 2 intermittent errors 502 bad gateway and 400. I have posting this to ms teams repo but, there is almost no response.

OfficeDev/BotBuilder-MicrosoftTeams#124

Code Example

Just added ms team channel on the bot service and using following TeamsChatConnector.

`
var teams = require("botbuilder-teams");

var connector = new teams.TeamsChatConnector({
appId: process.env.MICROSOFT_APP_ID,
appPassword: process.env.MICROSOFT_APP_PASSWORD
});
`

Reproduction Steps

Issue happens in the middle of the conversation at anytime. The message (output) from bot service is just dropped or never sent back to the user when 502 / 400 occurs. Full stack trace could be found on above issue link.

Expected Behavior

The output my bot services is generating should be sent back to user by ms teams channel and no errors in the logs.

This is what app insights shows. I see lots of 502 and 404.

Hi RJ. So far I'm not able to track down what's going on with your bot. Can you post your github link to this bot for me so I can see if it's something in the code?

@jwiley84 , I actually copy pasted this code and using it
https://github.com/Microsoft/BotBuilder/blob/master/Node/examples/basics-oauth/app.js

Alright, let me see what I can do.

RJ: Apologies! I haven't forgotten you! I'm still investigating.

Sure, thanks for the update.

Hi RJ. Again, sorry for not getting back to you soon. I'm trying to recreate your issue and have reached out to some coworkers for assistance.
You posted an image of your app insights with the 401 and 502s to smba.trafficmanager.net, do you have any where the POST requests went through just fine and you got a 200 or 202? We'd like to see the Remote dependency name of a successful POST request to that event.

Closing for lack of response.
