Binance stops streaming

Exchange
Binance, Binance Futures

Subscription type
Ticker

Describe the bug
I noticed recently Binancea and Binance Futures stops streaming data randomly. I tested with ticker streaming (!ticker@arr) and if i restart it, then it start working again. However, it stops again after few hours.

Note: There is no error in console

I also tested aggTrade endpoint and it works great and not stoping at all.

Anyone experiencing similar issue?

Thanks for submitting an issue!

Any chance you see a disconnected event when this happens? There is a flag that checks if tickers are subscribed. It only get cleared during the closing event but not disconnected. I'm guessing this is an issue with the socket gets disconnected and when it reconnects it fails to resent the !ticker@arr message because the flag hasn't been cleared.

Thanks for the reply.

There is nothing in console log about disconnected event. Do i need to console any specific variable to monitor disconnects? If, yes please let me know which one.

You need to attach an event listener to the disconnected event:

client.on("disconnected", () => console.log("disconnected"));
client.on("reconnecting", () => console.log("reconnecting"));
client.on("connecting", () => console.log("connecting"));
client.on("connected", () => console.log("connected"));

Thanks, I will attach these events and let you know

hi there @bifot are those happening in sequence immediately one after the other ? I noticed there is no "disconnected" event apart from the first ?
did you manage to find a solution or are you experiencing the same issue still ?

Experience this issue as well

[bifot]

i'm not experiencing this issue anymore, just installed latest version of ccxws and everything is fine

one year ago i was experiencing this issue because sometimes i did unsubscribe before fetching all markets (and subscribe after as well) and request on fetch markets failed so subscribe didn't triggered
