I have a bot using the API python-binance to place orders in the market in several accounts at the same time.
All the information about the market is being acquired via websocket, so I am sure this is not the problem as it is using another stream of communication for asking the market info then for placing the orders.
After several hours working, the bot gets errors like “Connection reset by peer”, or the one I am attaching here. The object of the connection is rejected by Binance, even with a very very low activity (it places orders every 1-2 hours and no more than 2.) I am pretty sure that is not a code problem as it works without any problem for 6-8 hours but then Binance decides to disconnect it.
My questions:
Why is this happening to my bot?
What are the desconnection rules of the Binance API for checking if I am missing something
A single connection to stream.binance.com is only valid for 24 hours; expect to be disconnected at the 24 hour mark
The websocket server will send a ping frame every 3 minutes. If the websocket server does not receive a pong frame back from the connection within a 10 minute period, the connection will be disconnected. Unsolicited pong frames are allowed.
Ensure that your code is ready handle any disconnection pass the 24 hour mark and also that your websocket library will reply a ping frame automatically.
Both things are covered in the code, and anyway we keep getting disconnected.
As you can see, the error is not with the stream, is with the rest API connection to place orders. We follow every step in the documentation and anyway keep getting disconnected. Please can you try to help us with other solutions?
Do this errors tell you something? “HTTPSConnectionPool(host=‘api.binance.com’, port=443): Read timed out. (read timeout=10)” It is from the rest API, and we are not getting data from there, so it is not caused by stressing the network. As you can see, there is no HTTP error so we are not getting disconected because of the limits
You should try, try+except and recreate your client to connect again with your api and security key in exception and have to pass or continue the program. I hope it will work.
