I have the latest version of EpiServer on my Windows server 2016 and almost every minute I have this warning on my event log:
WebSocketException
The WebSocket instance cannot be used for communication because it has been transitioned into an invalid state. at System.Web.WebSockets.AspNetWebSocket.ThrowIfAborted() at System.Web.WebSockets.AspNetWebSocket.CloseAsyncImpl(WebSocketCloseStatus closeStatus, String statusDescription, CancellationToken cancellationToken, Boolean performValidation) at System.Web.WebSockets.AspNetWebSocket.CloseAsync(WebSocketCloseStatus closeStatus, String statusDescription, CancellationToken cancellationToken) at EPiServer.Shell.UI.Messaging.Internal.DefaultWebSocketHandler.d__7.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at EPiServer.Shell.UI.Messaging.Internal.PushMessageHandler.d__7.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Web.WebSocketPipeline.d__9.MoveNext()
How can I fix it?
