Some times can not sub md quote normally

the same code,It can build the socket after get token: connect socket,received ‘o’ and send token and receove 200 , in demo host.
but yesterday,I found I can sub the quote and chart data normally,the log :sub MNQM2 Quote result:{“mode”:“RealTime”,“subscriptionId”:2553028},and socker listener just receive one frame data.
restart my program is not good. so what the problem?

Hi @zhangdc007. I may need more info, but it could be a few things. First, were you listening during market close hours? That would give you successful responses but wouldn’t show data until the market opens up again.

yes ,I sub in a close time,but It has no data in open time,and I wake up in 9:00am UTC+8 zone, it still no data

now I restart program,I copy the log about socket (log time is UTC+8 timeZone)

What environment are you using to build this? Are you possibly using Python websocket client and asyncio? Your logs look similar to some Python user’s I’ve worked with. I’ve seen some people have difficulties with that particular Python setup - it can be complicated to get the websocket to send heartbeats without blocking the async loop.

I use java ,and the ok http lib for build websocket ,May be I need change the websocket lib and try again

java can easy use multi thread ,I regist a schedul task to send heart beat for every socket after build session.and the heart beat recevie and send log seem ok

thanks ,when I try to change websocket lib,I found I has miss log the error call back,and I make up the error log,I find the BUG: it is the null point error in socker call back thread,so the MD socker is down when I has catch the NPE ,

the date delay is good!
the log is 2 sencod chart and the quote data, sencod chart delay is 800~1470ms ,quote data delay is 19~56ms
