How to fix mediaInitializationFailure: Media platform failed to initialize and 'Could not find a matching certificate for thumbprint'

Question

Hi I am trying to run https://github.com/microsoftgraph/microsoft-graph-comms-samples/tree/master/Samples/PublicSamples/EchoBot locally using ngrok free account. Since we need to tunnel both HTTP and TCP ports so used cloudfare.

Using cloudfare created two tunnels for the domain. Created a PFX certificate and got Thumbprint for the certificate.

While running the echo bot locally, I am getting below error:

mediaInitializationFailure: Media platform failed to initialize and 'Could not find a matching certificate for thumbprint'

Attached is the screenshot of the code and error is at builder.SetMediaPlatformSettings(mediaPlatformSettings);

Any help to resolving this error is welcome and also if anyone provides steps to run the echo bot to get audio stream from Teams meeting using ngrok is welcomed

Answer 1

The issue was due to the certificate was installed for the Current User and the code was referring to the Local Machine. After installing the certificate for local computer the issue got resolved
