Offering supreme security and portable authentication, proxy servers have evolved considerably over the last 50 years. E-commerce accounted for nearly 19% of global retail sales in 2022, and forecasts indicate by 2027, the online segment will make up to a quarter of total retail sales worldwide. So, finding a reliable proxy solution has never been more crucial for valuable data collection and fixing security vulnerabilities.

Web scraping software helps companies extract crucial data in real time, and the market for this software is set to cross the USD million threshold by 2030 . But even with limitless flows of constantly updated information at our fingertips, proxy error codes can make the web scraping process time-consuming and tedious.

So, what exactly causes proxy errors, and how can you fix them? Whether you’re a leader looking to understand their development team’s pain points better or simply expanding your knowledge on proxy error codes, here’s everything you need to know to solve them.

What Is a Proxy Error

Proxy servers act as a “middleman” between a user’s devices and the websites they browse. They keep the original IP address location hidden, and other potentially sensitive data confidential. A proxy error occurs when a request is sent to a web server through a proxy, but it doesn’t succeed. When this happens, an HTTP error status is generated, which usually bars access to the desired website or URL.

Each code reveals whether a specific HTTP request has been successfully completed. But with so many codes to decipher, the world of proxy error codes can be very confusing! To make it clearer, each HTTP status code is separated into five categories.

How Are HTTP Status Codes Categorized?

Similar to the influence the SOC 2 compliance checklist has on assessing and addressing the risks connected to third-party technology services, HTTP response codes are essential for troubleshooting website issues, improving search engine optimization (SEO), and more.

http status codes

As part of the HTTP standard, the first digit of the status code determines one of five standard classes of responses. These are:

HTTP Status Code Category Meaning
1XX (100-199) Informational responses Request received and being processed.
2XX (200-299) Success responses Request successfully received and accepted.
3XX (300-399) Redirectional responses Further action needed to complete request.
4XX (400-499) Client Error responses Request contains mistakes and can’t be completed.
5XX (500-599) Server Error responses Server failed to complete supposedly valid request.

For example, if we were trying to obtain a client’s details from a proxy server via CRM contact center integration and it generates a 200 OK HTTP status code, the request has successfully recalled the desired information.

What Are the Common Proxy Error Codes?

As you can see, the main types of HTTP proxy error codes are 4xx and 5xx, with 4xx indicating the error lies with the client and 5xx an issue with the server.

Maybe you want to buy domain name Australia to help people find you, but every time you go to the webpage, an error code pops up. No matter what you’re trying to do, with so many error codes to explore, it can be very overwhelming.

So, instead of overloading you, we’ve covered the top five proxy error codes you’re most likely to experience, the meaning behind them, and possible solutions to fix them.

Proxy Error Code Meaning Possible Solution
401 error Unauthorized response;
Requuest has not been applied as it lacks valid authentication credentials for the target resource.

403 error Forbidden;

Double-check the URL / Modify file permissions / Deactivate and reactivate plugins.
404 error Not Found;

407 error Proxy Authentication Required;

502 error Bad Gateway;
