Ethereum: Binance WebSocket Stream via Proxy Issue

As an Ethereum developer, you’re probably no stranger to the importance of reliable, high-performance data channels. However, when it comes to pulling data from a popular cryptocurrency exchange like Binance, things can get complicated quickly.

One common issue that users face is an incorrect error message, specifically websocket._exceptions. In this article, we’ll dive into why you’re seeing this error and provide you with a few possible solutions to fix the problem.

What’s Going On Behind the Scenes

When you’re using a proxy server to pull data from Binance, it can cause issues with WebSocket connections. Here’s what happens:

• Proxy Server Issues

  : Most proxies are designed to work with HTTP traffic, but when used for WebSocket connections, they often introduce additional overhead and latency.

• Connection Timeout: When the proxy server times out or encounters an error, it may prevent the WebSocket connection from establishing a stable connection to the Binance servers.

• Invalid Stream Data: Even if the proxy connection is successful, the Binance servers may return invalid stream data, which will cause a “websocket._exceptions” error.

Issue with websocket._exceptions

The “_exceptions” part of the error message refers to the fact that WebSocket connections use a separate protocol (JSON-RPC) over WebSocket. This allows for more complex and asynchronous data exchange between clients and servers. However, some of this complexity is lost when using proxies, leading to errors like “websocket._exceptions”.

Solution

To resolve the issue, you can try the following:

• Use a better performing proxy: Opt for a private proxy server that is optimized for WebSocket connections, such as Cloudflare Proxy or FastProxy.

• Configure your proxy server correctly

  : Make sure your proxy server is configured to use HTTP/1.1 and not HTTP/0.9, which can cause issues with WebSocket connections.

• Disable proxies in Binance settings: Go to the Binance API panel and disable all proxies in their settings.

• Use a custom proxy: Create your own proxy server that uses WebSockets and is optimized for your specific use case.

Additional Tips

• Make sure you are using the latest version of the @websockets/wss package to ensure compatibility with Binance’s WebSocket stream.

• If you are having issues with multiple proxies, try isolating the issue by disabling all but one proxy.

• Consider upgrading to a newer Ethereum blockchain (e.g. Ethereum 2.0), which may be better suited for high-performance data channels.

By following these troubleshooting steps and tips, you should be able to resolve the issue of getting websocket._exceptions when loading a WebSocket stream from Binance using a proxy.
