Traffic from MS Teams conversational bot not reaching bot through Azure Application Gateway

Question

The bot application is hosted in AKS and service is exposed via azure application gateway. Traffic from webchat is logged in AzureDiagnostics table, but traffic from Teams is not reaching the application gateway, meaning no logs of traffic. But when the endpoint of the same appID is changed to a self-hosted URL traffic is reaching the service.

Note: Application gateway is configured with external public DNS, well known CA certificate, multi site listener and WAF disabled

Is there anyway to trace traffic from azure bot service to the endpoint?

Edit: Enabled Application Insights, with which the message seems to reach Microsoft.BotService. But it does not in turn reach Application Gateway.

When a user is on Teams and starts a conversation with the bot hosted in AKS, are they able to maintain that conversation or does it fail? Is it just the logging that isn't captured? If so, I suspect it's because Teams maintains their own servers separate from ABS. Web Chat traffic is run via ABS as a web app utilizing Direct Line. Teams does not. The BotFramework connector is able to receive and send the messages to Teams but logging is not accessible via ABS outside of the traffic sent between the bot and the connector. — Steven Kanberg
@StevenKanberg, The conversation does not reach the bot hosted in AKS :(.. though I do not get any error on the teams client. Usually when there is something wrong while sending the message there would be an error in teams client.. "Message could not be delivered" of that sort. but in this case no errors and the logs are populating in application insights from teams client to connector but it is not reaching the bot — Ramakrishnan S
There is a possibility you need to tell your app service to accept the Teams service URL. Normally, the lack of this generates a 401 Unauthorized error, but the error might be getting lost in the traffic. Try adding the TrustServiceUrl(), as described here, and let me know if it works. — Steven Kanberg

Corebot-app-insights demonstrates how to add telemetry logging to your bot, storing telemetry within Application Insights.
