HTTP response code: 0
HTTP response body: null

how can I resolve this error. please
Hello @maasyi1224 ,
It could be a network issue on your side, such as blocked by firewall.
Could you please try with a tool like wscat ?
wscat -c wss://ws-api.binance.com:443/ws-api/v3
Connected (press CTRL+C to quit)
You should see “Connected”, if it doesn’t show ‘Connected’ then it means that the host can’t be reached from your machine.
Please let us know the result.
Thank you.
