Ethereum API Connection Issues with Binance Python Websocket

I have encountered a frustrating issue while trying to connect to the Binance WebSocket API using the Python library python-binance. Despite following a reputable guide, I am unable to establish a successful connection.

Error Messages:

The error messages from my attempt to connect to the API are as follows:

[Errno 10054] Connection refused
[Errno 10060] Connection aborted by the principal

These errors indicate that the Binance WebSocket server is either refusing or re-establishing its connection.

Troubleshooting Steps:

To resolve this issue, I have taken the following troubleshooting steps and improved the connection:

• Verify Binance API credentials: Make sure that I have set my Binance API credentials correctly. The tutorial available at recommends using environment variables or a .env file.

• Check the WebSocket port: Make sure that the WebSocket port (8443) is open and accessible on the Binance server. You can check this by searching for “Binance WebSockets” in your web browser’s address bar.

• Use the websocket-connection library: Consider using a more reliable library, such as websocket-connection, which provides better error handling and connection management.

• Check the WebSocket connection status:

  Make sure that the WebSocket connection is established by checking the Binance API console or via an external tool like wscat.

Updated code:

To demonstrate the issue, I will provide a simple example code snippet using both python-binance and websocket-connection. Please note that you may need to modify this code to suit your specific requirements.

import asyncio
import websocket





Binance API credentials (replace with your actual credentials)
api_key = "YOUR_API_KEY"
api_secret = "YOUR_API_SECRET"
async def main():
asynchronous with websockets.connect("wss://paper-api.binance.com:8443") as websocket:

Send a message to WebSocket
await websocket.send(f"Hello, Binance!")

Run an asynchronous function
asyncio.run(main())

import asyncio
import websocket
async def main():
asynchronous with websocket.client.create_connection("wss://paper-api.binance.com:8443") as ws:

Send a message to WebSocket
await ws.send(b"Hello, Binance!")



Run the asynchronous function

asyncio.run(main())

Conclusion:

After researching and troubleshooting various problems, I found that the primary cause of my connection problem lies in the incorrect use of the python-binance' library. Using a more reliable library likewebsocket-connection` can help solve similar connection problems.

If you’re having trouble connecting to Binance’s WebSocket API using Python, make sure you’ve set up your credentials correctly and make sure a WebSocket socket is available on Binance’s server.
