ping/pong heartbeat fails, disconnecting the app from websocket

Open HikaGenji opened this issue 4 years ago • 6 comments

the app connects to the public websocket, subscribe to some market data, e.g. ticker ETH-BTC then i get this after a few pings:

trace:

java.net.SocketTimeoutException: sent ping but didn't receive pong within 20000ms (after 0 successful ping/pongs) at okhttp3.internal.ws.RealWebSocket.writePingFrame(RealWebSocket.java:545) ~[okhttp-3.14.9.jar:na] at okhttp3.internal.ws.RealWebSocket$PingRunnable.run(RealWebSocket.java:529) ~[okhttp-3.14.9.jar:na] at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) ~[na:na] at java.base/java.util.concurrent.FutureTask.runAndReset(FutureTask.java:305) ~[na:na] at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:305) ~[na:na] at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) ~[na:na] at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) ~[na:na] at java.base/java.lang.Thread.run(Thread.java:834) ~[na:na]

Remove this code pingInterval(20, TimeUnit.SECONDS) at com/kucoin/sdk/factory/HttpClientFactory.java:32 maybe work.
