WebSocket disconnecting socket @ 3mins 20 seconds (Xamarin PCL) about websocketlistener HOT 9 CLOSED

Which version are you using, on which framework and how are you configuring the component?

I have never seen anything like that before.

from websocketlistener.

2.1.3 as a Xamarin PCL project...IOS and Android.

Listener works fine, and so does plain WebSocket...except for the fact the underlying TCP connection closes @ ~3:20 without generating any notification. The Websocket object continues to report Open, but the socket is closed and disposed.

also, this is a pull from git, not the nuget package. It was necessary to use the default buffer, not buffer manager, and remove some of the .Net logging statements to get it to compile for PCL IOS and Android. Neither of those mods were otherwise significant.

2.1.6 pull compiles without mods. But it still closes the underlying socket.
Tried engaging the server with a stimulus/response exchange of a couple of bytes every 30 seconds, but this had no effect. Neither did setting KeepAlive to 30 seconds.

What happens when the socket is closed and you try to send something? Does it throw an exception?

from websocketlistener.

That was a yes. We've tested and know the server is not terminating. And no
Close request is ever recieved. Breaking inside the while state.open loop shows the underlying socket is gone. An AsyncSend provokes the exception.

from websocketlistener.

Humm.. I will improve the connection detection mechanism, but the reason why is disconnecting after 3m 20s... I have no idea.

from websocketlistener.

Sorry that exception with stack trace you posted, is coming from the built-in client in the framework (System.Net.WebSockets.ClientWebSocket), no from WebSocketListener. Do you get any exception in WebSocketListener?
