Trouble Accessing Azure WCF relay Getting "The endpoint was not found. Endpoint does not exist." Error

I have been trying to use Azure WCF relay with two ASP applications as Given in the link

https://docs.microsoft.com/en-us/azure/service-bus-relay/service-bus-dotnet-hybrid-app-using-service-bus-relay

the example explains to create a console server and MVC Client application to connect using azure service bus relay.

I created RootManageSharedAccessKey as mentioned and Given primary key to both of the applications.

However after implementation of the same, I have been getting this issue.

Endpoint= http://mynewns01.servicebus.windows.net/products
SharedAccessKey
