websocketMarketdemo运行失败

[tsuribaka]

我下载了master的代码，cmake&make之后，运行websocketMarketdemo 出现异常。

root@xxx:/home/xxxx/websocketMarket/build# ./websocketMarketdemo
market.htusdt.kline.1min
enter any key to quit
terminate called after throwing an instance of 'web::websockets::client::websocket_exception'
what(): set_fail_handler: 9: Timer Expired
terminate called recursively
Aborted (core dumped)

这个是因为什么原因造成的？是URL错误吗？
