SignalR connection closed while refreshing the page

Im using SignalR for real time notification. My problem is that, after initiating connection to the server HUB, the connection gets disconnected if I refresh the page. Can anybody give me an idea why the connection gets disconnected on every page refreshes. 

public class TaskHub : Hub 
{
   public void AddSession(string sessionId) 
   {
       Groups.Add(Context.ConnectionId, sessionId); 
   } 
}

DI container : Hub must work singleton

builder.RegisterType<FeedHub>().ExternallyOwned().SingleInstance();

You manage OnReconnected event in hub.

public override Task OnConnected()
{
      ...
      return base.OnConnected();
}

public override Task OnReconnected()
{
     ...
     return base.OnReconnected();
}

public override Task OnDisconnected(bool stopCalled)
{
     ....
     return base.OnDisconnected(stopCalled);
}
