Ethereum: Binance WebSocket Stream via Proxy Issue
As an Ethereum developer, you’re probably no stranger to the importance of reliable and efficient data feeds. However, when it comes to retrieving data from a popular cryptocurrency exchange like Binance, things can get complicated quickly.
One common issue that users encounter is incorrect error messages, specifically “websocket._exceptions”. In this article, we’ll take a look at why you’re seeing this error and offer potential solutions to resolve the issue.
What’s happening behind the scenes
When you use a proxy to retrieve data from Binance, it can cause issues with WebSocket connections. Here’s what happens:
- Proxy issues
: Most proxies are designed to work with HTTP traffic, but when used with WebSocket connections, they often cause additional overhead and latency.
- Connection timeout: When the proxy server times out or encounters an error, it can prevent the WebSocket connection from establishing a stable connection to Binance servers.
- Invalid streaming data: Even if the proxy connection is successful, Binance servers may return invalid streaming data, causing a “websocket._exceptions” error.
Websocket._Exceptions issue
The _exceptions part of the error message refers to the fact that WebSocket connections use a separate protocol (JSON-RPC) over WebSockets. This allows for more complex and asynchronous data transfer between clients and servers. However, when using proxies, some of this complexity is lost, leading to errors such as “websocket._exceptions”.
We will fix the problem
To resolve the issue, you can try the following:
- Use a proxy with better performance: Choose a private proxy that is optimized for WebSocket connections, such as Cloudflare Proxy or FastProxy.
- Configure the proxy correctly: Make sure your proxy is configured to use HTTP/1.1 and not HTTP/0.9, which can cause problems with WebSocket connections.
- Disable proxies in Binance settings: Go to the Binance API dashboard and disable proxies in their settings.
- Use a custom proxy: Create a custom proxy that uses WebSockets and is optimized for your use cases.
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 of the proxies.
- Consider upgrading to a newer Ethereum blockchain (e.g. Ethereum 2.0), which may be better suited for efficient data feeds.
By following these instructions and troubleshooting tips, you should be able to resolve the issue related to “websocket._exceptions” when accessing Binance’s WebSocket stream using a proxy.
