Joining a Call (Establishing) takes forever

[dmklementiev-zz]

I am following instructions from this document. When I click on the Join a Call, the status changes to "Establishing" that never (at least 20 minutes) ends.

I set up my meeting so Everyone bypasses, but this didn't change anything. Please let me know what would be the best way to investigate.

Here is the log:

Ping :) Is there any other information I can collect to help to resolve this issue? Also can you suggest any steps to debug/narrow down the problem (break point, logs, etc.) that I can take?

Hi dmklementiev. It seems that the bot cannot establish the handshake with the Media Platform, but this time doesn't throw an exception like the last time. Most of the time is due to a mistake in the configuration of the bot. I don't know if you modified your logs, but the outgoing request has a wrong callback URL "callbackUri": "https://.ngrok.io/api/bot/calling". Regarding suggestions/steps to debug/narrow down the problem, we haven't developed the core libraries of the application-hosted media bots so when we had those types of issues, we generally opened issues in the following [GitHub repository] (https://github.com/microsoftgraph/microsoft-graph-comms-samples) and reviewed our configuration (DNS, Certificate, BotConfiguration, etc). We are not experts reading those logs, but after troubleshooting many times, we can sometimes identify issues.
