Async void error. ADTDataHandler on ADTConnection has been disabled. about mslearn-mr-adt-in-unity

I've also been getting this error recently but get a 404 (Not Found) I've read online that it might have to do with the SignalR managed assemblies that are in the Unity project being out of date and don't work with the Azure SignalR service running in the cloud.

Below is the output from my project today.

404 (Not Found) -- Async void error. ADTDataHandler on ADTConnection has been disabled.

@jpietila78 Double check you have something like this https://myprojfuncappxxxxxxxxxx.azurewebsites.net/api in the Url field in the ADTConnection Prefab without the /negotiate that is what fixed my 404 error. Check out this step for more info.
