Middleware Error

[BurakOgutken]

First of all, great job on the OCPP backend software you've created. We are trying to integrate our station software with your backend, but intermittently, we are encountering the error I shared below on the middleware side. We haven't been able to understand the cause. Could you help us figure it out?

 Microsoft.AspNetCore.Server.Kestrel[13]
      Connection id "0HN7D91NRVPPK", Request id "0HN7D91NRVPPK:00000001": An unhandled exception was thrown by the application.
      System.Net.WebSockets.WebSocketException (0x80004005): The WebSocket is in an invalid state ('Aborted') for this operation. Valid states are: 'Open, CloseReceived, CloseSent'
         at System.Net.WebSockets.WebSocketValidate.ThrowIfInvalidState(WebSocketState currentState, Boolean isDisposed, WebSocketState[] validStates)
         at System.Net.WebSockets.ManagedWebSocket.CloseAsync(WebSocketCloseStatus closeStatus, String statusDescription, CancellationToken cancellationToken)

It doesn't seem related to OCPP.Core but to websockets in general. You can google it yourself...
The websocket specification names some scenarios how connections come to an aborted state:
