[HikaGenji]

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)

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