Ethereum API Connection Problem on Linux: Troubleshooting Guide

As a cryptocurrency enthusiast, you have probably put in the time and effort to build a reliable trading script that uses the Binance API to connect to the Ethereum blockchain. However, after extensive troubleshooting, you are frustrated and wondering what is wrong.

In this article, we will delve into the possible explanations for the “APIError(code=-2015)” error on Linux that often occurs while connecting to the Binance API. We will also provide some steps that will help you fix the issue and ensure a smooth connection to the Ethereum blockchain.

What does APIError(code=-2015) mean?

The error code -2015 means that there was an error in the HTTP request sent by the Python script to the Binance API. This error is usually caused by a network issue, such as a DNS issue or a timeout, rather than a programming error.

Common causes of APIError(code=-2015)

Here are some possible reasons why this error occurs:

• DNS Resolution Issues: The Binance API may not be able to resolve the domain name api.binance.com due to a DNS resolution issue on Linux.

• Timeouts: The API request may have timed out, resulting in error code -2015.

• Network Connectivity Issues: An internet connection issue or a firewall blocking outbound traffic may also cause the API to fail.

Troubleshooting Steps

To resolve the issue, please follow these steps:

• Verify your Binance public API key: Make sure you are using the correct public API key and not an API key with a shorter expiration period.

• Check network connectivity: Check that your internet connection is stable and working properly.

• Update your Python script to handle retries: Consider adding retry logic to your Python script, allowing it to attempt API requests up to 5 times before giving up.

• Disable proxy settings: If you are using a proxy, try disabling it or setting the http_proxy and https_proxy environment variables to disable it.

• Use a different port for the Binance API: Some users have reported success by specifying a non-standard port (e.g. 443) instead of the default port (80).

• Check Binance API documentation: Make sure your Python script is using the correct API endpoint and authentication method.

Additional troubleshooting steps

If none of these steps resolve the issue, you can try:

• Check Binance API status: Visit the Binance API status page to see if there are any known issues or if there is scheduled maintenance.

• Use a different API client library: Consider using a different Python library (e.g. binance-api-client) that may have better support for your specific use case.

• Contact Binance customer support: If none of the above steps resolve the issue, please contact Binance customer support for further assistance.
