Connection Reset by Peer: Understanding the Error and Troubleshooting Tips

Introduction:

In the vast landscape of networking and communication, errors often occur that can interrupt the flow of data between different devices or services. One such error, frequently encountered by internet users, is the “Connection Reset by Peer” error. It appears when a connection between two devices is terminated unexpectedly by one of the peers, typically due to various reasons such as network issues or misconfigured settings. In this article, we will delve into the details of Connection Reset by Peer, its causes, troubleshooting tips, and frequently asked questions to provide a comprehensive understanding of this error.

Understanding Connection Reset by Peer:

When establishing a connection between two devices or services, they exchange data packets to establish and maintain a stable connection. However, during this process, if one of the peers decides to terminate the connection abruptly, the other peer receives the “Connection Reset by Peer” error. The error essentially means that the remote device, server, or service has closed the connection before it could be fully established or completed.

Causes of Connection Reset by Peer:

1. Network Issues: Connection Reset by Peer can often occur due to network-related problems. These issues might include a sudden loss of internet connectivity, fluctuating signal strength, or disruption in the communication channel. In such cases, the connection is abruptly interrupted, resulting in the error message.

Python Requests Error 104: Connection Reset by Peer Explained

Python is a versatile programming language that offers an extensive range of libraries and frameworks for web development and various other purposes. One of the most widely-used libraries in Python for making HTTP requests is the “requests” library. However, like any software, it is susceptible to errors. One such error is the “Connection Reset by Peer” error, also known as Error 104. In this article, we will delve into the specifics of this error, its causes, and possible solutions.

### Understanding Python Requests Error 104: Connection Reset by Peer

Error 104 is a network-related error that occurs when a connection is unexpectedly terminated by the server while establishing a connection or during an ongoing communication. It is important to note that this error is caused by the server and not the client (your Python script using the requests library).

When you initiate an HTTP request using the requests library, the client establishes a connection with the server, sends the request, and waits for a response. In the case of an error 104, the server abruptly terminates the connection, resulting in an incomplete or failed request.

### Possible Causes of Error 104

1. **Server Overload:** One common cause of this error is when the server is overloaded with requests, and as a result, it forcefully closes some connections to manage the load. This can be a temporary issue, where retrying the request after a few moments may resolve the problem.

2. **Firewall or Proxy Restrictions:** Some networks employ firewalls or proxies that restrict certain requests or protocols. These restrictions can result in the server abruptly closing the connection, leading to an error 104.

3. **Network or Connectivity Issues:** Unstable network connections, intermittent connectivity, or network congestion can cause the server to terminate connections abruptly. Suppose the client experiences frequent network interruptions or high latency, resulting in slower response times. In that case, the server might terminate the connection, mistaking it for an inactive connection.

4. **Server Misconfiguration:** Server misconfigurations, such as incorrect server settings or security measures, can result in terminating connections unexpectedly. These misconfigurations can cause the server to reset the connection, leading to error 104.

### How to Resolve Error 104

Resolving error 104 requires a systematic approach to identify and address the underlying cause. Here are some steps you can take to troubleshoot and fix this issue:

**1. Retry the Request:** As mentioned earlier, error 104 can be temporary, caused by server overload. Retry the request after a short delay, allowing the server to recover from the load.

**2. Check Network Connectivity:** Examine your network connectivity to ensure it is stable, uninterrupted, and not experiencing any latency issues. You can try switching to a different network connection or restart your router/modem.

**3. Disable Proxy or Firewall:** If you suspect that proxies or firewalls are interfering with the connection, try disabling them temporarily. Ensure that the requests made by your Python script are not blocked by any network restrictions.

**4. Upgrade Requests Library and SSL:** Older versions of the requests library or outdated SSL versions might contain bugs or security vulnerabilities that can lead to connection issues. Upgrade your requests library and SSL to the latest versions to mitigate these problems.

**5. Adjust Connection Timeout:** By default, the requests library has a timeout period after which it terminates the request. You can try increasing the timeout value to allow for slower responses or high-latency connections.

**6. Verify SSL Certificate:** SSL certificate verification can sometimes cause a connection reset. You can try disabling certificate verification by passing `verify=False` as a parameter to your request, but this approach is not recommended in production environments.

**7. Contact Server Administrator:** If the issue persists, contact the server administrator or the API/service provider to inquire about any known issues, maintenance, or misconfigurations on their end that may be causing the error.

### FAQs

**Q1. Can the error 104 occur on the client-side?**

No, error 104 is always caused by the server terminating the connection abruptly. The client-side code, which uses the requests library, is not responsible for this error.

**Q2. How can I determine if the error is caused by server overload?**

If you suspect server overload, you can try accessing other resources on the same server and see if they respond properly. Additionally, checking the server logs for any indications of high load or resource exhaustion can help identify server overload.

**Q3. Is there a way to regain the lost data from a connection reset?**

No, when the connection is reset by the server, any data sent or received during that connection is lost. It is necessary to handle this situation gracefully by retrying the request or informing the user of a failure.

**Q4. Should I always disable SSL certificate verification to avoid error 104?**

Disabling SSL certificate verification is not recommended, especially in production environments. It exposes your application to potential security risks. It should only be used as a temporary troubleshooting measure and should be accompanied by further investigation and resolution of the underlying cause.

In conclusion, Python Requests Error 104: Connection Reset by Peer is a network-related error that occurs when a server abruptly terminates a connection. This error can have various causes, including server overload, network issues, proxies/firewall restrictions, or server misconfigurations. By following the troubleshooting steps mentioned and contacting the server administrator if necessary, you can mitigate and resolve this error, ensuring smoother web scraping or API interactions with Python requests library.
