The way I use nodejs in @binance/connector to connect websocket, wss://testnet.binance.vision connects successfully, but when using default address Error: WebSocket was closed before the connection was established, after some time
Has this happened once or is it a consistent behaviour?
Every time, in Figure 1, I found that the settimeout time is too short, but Figure 2 happens every time, and it will start receiving data after about 12 minutes, and it has not been solved yet. 
Please try using different machines to further diagnose the issue. Does this happen for other websocket apis such as the Futures Websocket?
Thank you for your answer， i will try it，If it works that’s really helpful 
I tried your suggestion, using the example in @node-binance-api to get the kline of futures, but it still got 1006 error, and I used websocket in my vue-web project to connect easily
After 12 minutes I got the data from the server, every time
