Common Server Error Messages
Contents |
You request a resource, such as web page or an image, and you get back a response, or your browser does, at least. Thanks to the "http:" you place before a URL when you type in the browser’s address bar, requests and responses have a predefined structure. As common error messages in java defined by the Hypertext Transfer Protocol (HTTP), an important part of that structure is a status code. common error messages windows Introducing HTTP Status Codes Status codes are three-digit numbers. A 200 code is the most common and represents a successful response. The first digit defines what

is known as the class of the status code. If the code starts with a 2, as in 200, that represents a successful response to the request. There are status codes that start with 1. These represent informational messages. These are rarely seen.
Server Error Codes
A code of the form 3xx represents a redirection response. Typically, the browser will handle these without user interaction and get the resource from the new location instead. Error codes come in the form of 4xx and 5xx statuses. Error codes at the 400 level mean there was a client-side error — think of something like the user typing the wrong URL in the address bar. Error codes at the 500 level mean there was a server-side error — think of something like the database server going down dell server error codes or perhaps running out of disk space. Five of the most popular error codes are 403, 404, 500, 503, and 504. Let’s look at each of these in a little more detail. 404 Not Found The most common error code you run into is a 404 error. The 404 status code means the requested resource is no longer available or, more specifically, just not found. Was it ever available there? You don’t know. You do know it isn’t available there now. What are some of the reasons for a 404 error? Typos are a common reason for getting a 404 error. A missing or extra letter in a typed-in url, or a wrong domain name can often result in a 404 error. Another reason for 404 errors isn’t typos; it is the aging of the web. When someone writes an article or blog, that person might link to a secondary source to provide additional information for the article. Now imagine revisiting said article six months or six years later. If what was linked to is no longer on the web, a 404 error will be generated when you click on the link in the browser. 403 Forbidden Another common client-side response status code is 403. Getting a 403 status code back from an HTTP request means access to the resource is forbidden. This is not an authentication problem; those are 401 (unauthorized) errors. One common reason for 403 errors is the server maintaining a whitelist of machines that can access that system and the user’s ma

Understanding Status Codes Behind every error page you see on the web there is an HTTP status code sent by https://www.globo.tech/learning-center/5-most-common-http-error-codes-explained/ the web server. Status codes come in the format of 3 digit numbers. The first digit marks the class of the status code: 1XX status codes have informational purposes 2XX indicates success 3XX is for redirection None of these three classes result in an HTML error page as in this cases the client knows what to do and goes on with the task without hesitation. What we usually see are the 4XX and 5XX kind: 4XX http://www.hongkiat.com/blog/common-http-errors/ represent client-side errors 5XXs indicate problems on the server side HTML error pages are displayed in these cases because the client has no idea about what how to move on. Let’s see what happens in the background when something goes south and what you can do about it. Client-Side Errors (4XX) 1. 400 – Bad Request Whenever the client sends a request the server is unable to understand, the 400 Bad Request error page shows up. It usually happens when the data sent by the browser doesn’t respect the rules of the HTTP protocol, so the web server is clueless about how to process a request containing a malformed syntax. Pin itWhen you see a 400 error page the reason is most likely that there’s something unstable on the client side: a not sufficiently protected operating system, an instable internet connection, a defective browser or a caching problem. So it’s always a good idea to test a bit your own PC before you contact the owner of the website. Open the same webpage in a different browser, clear the cache, and check if you are due with security updates. If you regularly meet the 400 error on different sites, your PC or Mac is awaiting a thorough security checkup. 2. 401 – Authorization Required When there’s a password-protected web page behind the client’s request, the serve

This guide will help you understand exactly what each error page means and what to do when you see them. Note that each browser displays and words its error pages differently. A certificate server error error or malware warning looks different in each different browser, but the different types of error pages mean the same thing. Certificate Error An SSL certificate error or security certificate error indicates a problem with HTTPS encryption. You’ll only see this error when connecting to a website using HTTPS. When using HTTPS encryption, websites present certificates to identify that they are legitimate. For example, Google.com has a security certificate issued by a trusted certificate server error codes authority. The certificate authority verifies that Google is the real owner of Google.com and is entitled to the certificate. When you connect to Google.com using HTTPS, Google presents this certificate. Your browser checks that the certificate was issued by a known legitimate certificate authority to verify you’re connecting to the real Google.com, not another server pretending to be Google.com. When you see a certificate error, this indicates that you’re not necessarily connecting to the real, legitimate website. For example, if you try to access your bank’s website on a public Wi-Fi network and see this error, it’s possible that the network is compromised and someone is attempting to impersonate your bank’s website. However, it’s also possible that a website failed to properly renew or configure its certificate. Either way, you shouldn’t continue when you see this error message. Phishing and Malware Warnings Your browser will also display phishing (or “web forgery”) and malware warnings. Whether you use Firefox, Chrome, or Internet Explorer, your browser regularly downloads a list of dangerous websites. When you attempt to connect to a website on this list, you’ll see an error message. Websites are placed on these lists because they contain malware or because they attempt to impersonate a real website to steal your passwords, credit card numbers, or other sensitive information. In
