I wrote some logic which represent near 200 websocet connection with exchange at the same time.I use third party api and it based on org.eclipse.jetty.websocket.api. I have this method which i had to override.

try {

            URI uri = new URI(websocketBaseUrl + url);

            SslContextFactory sslContextFactory = new SslContextFactory();

            sslContextFactory.setTrustAll(true); 

            WebSocketClient client = new WebSocketClient(sslContextFactory);

            client.setMaxIdleTimeout(0);

            client.start();

            return client.connect(adapter, uri).get();

        } catch (URISyntaxException  e) {

            throw new BinanceApiException("URL Syntax error: " + e.getMessage());

        } catch (Throwable e) {

            throw new BinanceApiException("Websocket error: " + e.getMessage());

        }

I added setIdleTimeout to it so that the connection is not lost when i don't recieve information for a long time.
Exchange close connection one time a day but for 2,3 sometimes 4 days it have been reconnected.But finally i get this:

I find this question on stackoverflow but i can't see clear answer. Pls help.Thanks in advance.

If you want the connection to stay open if idle, you should configure your client this way:

client.setMaxIdleTimeout(Long.MAX_VALUE);

Setting maxIdleTimeout to 0 would have the opposite effect: Closing the connection as soon as it becomes idle.
