Hello man.

It is my first post here.

Are you using the combined strams feature? If not, subscribing to 200 symbols simultaneously, it’s possible that the sheer volume of data or the number of connections is causing some strain.
To use the combined strams feature :

wss://stream.binance.com:443/stream?streams=symbol1@kline_1m/symbol2@kline_1m/...

Also, the error suggests a problem with keepalive pings. WebSockets often have a ping/pong mechanism to keep the connection alive. You can consider setting the ping_interval and ping_timeout parameters in websockets.connect() to manage the keepalive pings:

self.websocket = await websockets.connect("wss://stream.binance.com:443/ws", ping_interval=60, ping_timeout=180)

Hope my answer will help you,

Relative to streams, after create the url i need to send the subscribers?

I would do two things:

  • Try logging data
  • Try limiting the number of symbols you’re subscribing to see if error stops
  • I don’t know if I understand your question, but here is an example: wss://stream.binance.com:443/stream?streams=BTCUSDT@kline_1m/ETHUSDT@kline_1m/
