Description

After a few hours or when the Internet connection is lost, coinex websocket freezes and does not display any errors.

Code

import asyncio
import ccxt.pro

async def watch_coinex():
    # Coinex
    exchange = ccxt.pro.coinex({
                'apiKey': '',
                'secret': '',
                'enableRateLimit': True,
            })
    exchange.verbose = True

    while True:
        try:
            Coinex = await exchange.watch_order_book ('BTC/USDT', limit = 5, params = {})
            print(Coinex)

        except:
            print("fail")
            await exchange.close()

async def main():
    await watch_coinex()

asyncio.run(main())

For example, Mexc work fine:

import asyncio
import ccxt.pro

async def watch_mexc():
    # Mexc
    exchange = ccxt.pro.mexc({
            'apiKey': '',
            'secret': '',
            'enableRateLimit': True,
        })
    exchange.verbose = True

    while True:
        try:
            Mexc = await exchange.watch_order_book ('BTC/USDT', limit = 3, params = {})
            print(Mexc)

        except:
            print("fail")
            await exchange.close()

async def main():
    await watch_mexc()

asyncio.run(main())

Hello @bonusru, does it happen only after a few hours? Is there a way of reproducing it faster?

[carlosmiei]

@bonusru If you enable the verbose mode exchange.verbose = True can you see any errors in the logs?

Repeats if I turn off the Internet. exchange.verbose = True This doesn't help, it just hangs on the last update received, no errors
