When I ping the key always get
{"code":-1125,"msg":"This listenKey does not exist."}
please share which endpoint returned this error and what’s the parameter sent in the request?
thanks
http PUT with headers
headers.insert("User-Agent","Mozilla/4.0 (compatible; Node Binance API)");
headers.insert("Content-Type","application/x-www-form-urlencoded");
headers.insert("X-MBX-APIKEY", access_key);
https://api.binance.com/api/v3/userDataStream?listenKey=${listenKey}
ping every 10 minutes, always get This listenKey does not exist, then retry(generate a new key)
Why the listenKey could be invalid?

it seems that this listenKey is not valid, please try to generate a new one and PUT to renew.
it should work then 
Sorry this log is still very limited, I’m not sure how did you get this error.
But in order to renew the listenKey, it has to send a RESTful request
PUT /api/v3/userDataStream , providing the valid listen key for the parameter listenKey.
in cURL, can be like:
curl -H "Context-Type: application/json" --request PUT 'https://api.binance.com/api/v3/userDataStream?listenKey=xxxxx'
