What are HTTP Error Codes? Common Codes and How to Fix Them
Why Understanding HTTP Error Codes is Crucial?
Indeed, the role of server-side and client-side http status codes, as well as server error responses, is key to upholding an excellent website that offers a smooth user experience. As SEO specialists, understanding these server status and client-side errors can profoundly influence your website’s performance and web traffic. Search engines also frown upon webpages prone to errors, leading to lower rankings on results pages—making giving attention to HTTP status codes essential to Technical SEO.
Should your website encounter issues, perhaps due to a corrupted DNS or outdated resource url, you might face a DNS error or a common client-side error, the dreaded 404. Clearing the DNS cache can often be a quick solution to these issues. Understanding such client-side status error codes can offer insights into potential issues and help boost your domain’s performance.
Demystifying Common HTTP Errors for Beginners
HTTP error codes may seem daunting, but they’re actually quite straightforward. Each three-digit code begins with a digit between 1 and 5, representing the response type — informational (1xx), successful (2xx), a redirection (3xx), client error (4xx), or server error (5xx). In the realm of redirection codes, 300s indicate that a new resource has been substituted for the requested resource. At times, error codes like 502 or 504 may pop up, indicating issues with proxy settings or backend server connections. This 502 Bad Gateway error signifies that the server acting as a gateway or proxy did not receive a valid response from the backend servers that should fulfill the request. Similarly, a 504 status or Gateway Timeout error means that the server, acting as a gateway or proxy, didn’t receive a response from the backend in the allowed time frame. Properly paying heed to these redirect codes or request data patterns can help identify issues.
Notably, your server access log serves as an invaluable tool to monitor such server changes and inconsistencies in your web application. Thus, maintaining server logs plays a significant role. In-depth tutorial(s) can be beneficial in ensuring a suitable server configuration to avoid such conflicts. If trouble escalates beyond your understanding, don’t hesitate to take a peek into your server work or configuration manuals, or check your website’s IP address to locate and resolve inconsistencies.
HTTP Response Code Failure: A Glimpse into Client-Side Error Codes
Decoding the Enigma of 400 Bad Request
A 400 Bad Request error pops up when the server can’t understand your request due to invalid syntax. This error, compounded by the web browser mechanism, might surface when the user’s site-associated cookie is corrupt or there’s a malformed request stemming from an issue with a directory listing. Such a malformed request could originate either from a faulty browser session or from human error while manually forming HTTP requests. This problematic situation typically lies within the domain of browser mode operations or incorrectly configured www-data permissions, often necessitating thorough directory fixes. Analysis of such faults often underscores the importance of a solid default set-up to dodge these pitfalls. In times of persistent problems, a restart of the problematic services or even a modem might be required to rectify a connection timeout.
Everything You Need to Know: The 401 Unauthorized Computer Errors
The 401 Unauthorized error is an HTTP status code signaling that you need valid login credentials to access the page requested. Also referred to as “Authorization Required,” this error usually requires user authentication, demanding correct username and email details, much like a site admin would need for effective site management. Originating due to myriad factors, one could even consider it akin to a 407 Proxy Authentication Required status code when accessing some networks. Potential culprits could be outdated browser cache and cookies, which may obstruct the authentication process or configuration mistakes in your firewall. It may also arise from using an old incorrect URL or a DNS issue with your name server. Further inspection of log files can unravel the root of the problem, but always ensure Apache services are correctly configured, especially when employed as a reverse proxy server.
Disentangling the Web of 404 Not Found Error
404 Not Found is probably the best-known HTTP error. In short, the resource you’re searching for isn’t available on the server. Maybe you’re trying to find a page that no longer exists, or you’ve typed the URL incorrectly. Don’t neglect this one, as too many 404 errors might harm your SEO!
Journey through Server-Side HTTP Error Codes
Breaking Down the Meaning of the Dreaded 500 Server Error Codes
Ah, the 500 Internal Server Error, a seemingly all-encompassing code signaling something went haywire on the server. Causes can be various: server misconfiguration, PHP issues, database problems, and more. Sometimes, an unexpected 500 error may be due to reasons like the server’s inability to upgrade and support its protocol or perhaps, reaching its bandwidth limit after a system upgrade. It’s crucial to note that documentation is key in finding a resolution these issues. It’s a confusing, often frustrating error because its reason is unknown to the server itself. That’s when constructive feedback from friendly communities like the Umbraco can be a game-changer.
Understanding the Complexities of 502 Gateway Errors
The 502 Bad Gateway Error is a server-side status code meaning a server received an invalid response from another server. In terms of HTTP headers, the server receives, processes this invalid request, and sends back the error wrapped in an HTTP header. Picture this scenario: a stop along the way to your site— a node (or gateway) — has responded invalidly, purportedly due to a variety of reasons. This could span from server overload due to attacks, incorrectly formatted PHP code reminiscent of a Google media format error, or even connection disruptions initiated by firewall-oriented issues. Troubleshooting with a strategy similar to a refresh in Google chrome can often help to locate the problematic gateway. Remember, the process might involve a bit of trial-and-error before successful resolution.
Making Sense of 503 Service Unavailable: The Beast of Server Errors
A 503 Service Unavailable status code implies the server can’t process your request due to being overloaded or under maintenance. Perhaps an updated version of WordPress or an NGINX module is undergoing an update causing this issue. The server may struggle with not having enough CPU or memory resources to handle incoming requests, there is ongoing maintenance, or the web server needs user, thread, or process allowances tweaked. This can also happen when a website’s CMS uses too many modules, leading to overconsumption of resources. It’s alarming but usually temporary and it’s best to reattempt later. To avoid such situations, hiring a website company for regular maintenance proves useful.
Numbers Behind HTTP Errors: Causes and How to Overcome them

Sometimes, all it takes is a cache and cookies clearing, password reset, or even reloading the page.
Eradicating the Bothersome 404 Not Found Errors
Ah, the infamous 404 Not Found Error! Fixing it can involve several steps based on the root cause. If it’s due to a broken or dead link, or a URL change without proper redirection, solutions can vary.

Tools like a free website analyzer can be helpful in finding all 404 pages on your site. Remember, no issue is too big to resolve with the right information!
