Client Connection closes after ~60 seconds

Reproduce the client and server setup shown, using WebSocket.Connect and AddWebSocketService, while observing the roughly 60-second disconnect. Start with the WsFrame.ParseAsync and Ext.ReadBytesAsync stack-trace paths, then trace the close through Service.cs:56 and Service.cs:61. Done means the cause is identified and the connection no longer closes unexpectedly at that interval.

Good Morning STA!

I'm getting the following exception after approx 60 seconds of my client running:

I'm connecting with the collowing code

            Stopwatch watch = new Stopwatch();
            watch.Start();

            ws = new WebSocket("ws://localhost:8140/game");


            ws.OnMessage += (sender, e) =>
                this.Progress(e);

            ws.OnError += (sender, e) =>
                Console.WriteLine("Stopwatch: " + watch.ElapsedMilliseconds);

            ws.OnClose += (sender, e) =>
                Console.WriteLine("Stopwatch: " + watch.ElapsedMilliseconds);

            ws.Connect();
            this.Login(hash);

And my server looks like this:

            GameEngine gameEngine = new GameEngine();
            ChatEngine chatEngine = new ChatEngine();


            wssv.AddWebSocketService<GameService>("/game", () => new GameService(gameEngine));
            wssv.AddWebSocketService<ChatService>("/chat", () => new ChatService(chatEngine));
            wssv.AddWebSocketService<AdminService>("/admin", () => new AdminService(gameEngine, chatEngine));
            wssv.Log.Level = LogLevel.Fatal;

            wssv.Start();

            Console.ReadKey(true);
            wssv.Stop();

I logged duration of the connection three times, and i got the following timings:
57835ms First run
56207ms Second run
57343ms Third run

I'm not sure if this is something with websocket-sharp, but maybe you know the problem? 👍
