angular - Unable to obtain configuration from well-known/openid-configuration

I am using ASP.NET 5, In my solution I have Web API, Identity Server and Angular 2 project and I am authenticating Angular 2 client by using Identity Server, Angular 2 client consumes web api by passing token in http request and web api authenticate token and gives response, for this I have written a custom attribute which checks that user is authenticated or not

When I consume API I am getting following exception and Web API returns 500 internal server error.

System.InvalidOperationException: IDX10803: Unable to obtain configuration from: 'http://xx.xx.xx.x:3926/.well-known/openid-configuration'. ---> System.IO.IOException: IDX10804: Unable to retrieve document from: 'http://xx.xx.xx.x:3926/.well-known/openid-configuration'. ---> System.AggregateException: One or more errors occurred. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond xx.xx.xx.x:3926 at System.Net.Sockets.Socket.EndConnect(IAsyncResult asyncResult) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception)

If identityserver and the access token validation middleware are hosted in the same application there is a race condition at startup.

The validation middleware tries to load the discovery document, which is not yet available.

In these scenarios, set the DelayLoadMetadata flag on the validation middleware to true.

If you disable the discovery endpoint altogether, you need to configure the issuer and key material on the validation options.
