Before we get started, what\u2019s an HTTP error?<\/b><\/h2>\n

HTTP errors occur when you <\/span>want to go to a web address and the browser isn\u2019t able to access it<\/b>, which can happen for different reasons. <\/span><\/p>\n

The most common types of errors <\/span>start with the numbers 4 and 5<\/b>. Although there are error codes that start with 1, 2 and 3, you’re unlikely to encounter them when browsing. <\/span><\/p>\n

These error numbers are\u00a0usually followed by a short explanation, but they don\u2019t give you much information. So, we\u2019ll give you the full scoop on each of them below. <\/span><\/p>\n

What the most common HTTP errors mean <\/b><\/h2>\n

Error HTTP 404 (Not Found)<\/b><\/h3>\n

This error means that the page you want to access <\/span>doesn\u2019t exist at the moment. <\/b>This may be because you incorrectly entered the web address or because the page owners deleted it. It\u2019s possible that a page showing a 404 error won\u2019t have one later on, which means it\u2019s come back online. <\/span><\/p>\n

Error HTTP 403 (Forbidden)<\/b><\/h3>\n

This error shows up when you try to access a prohibited web page, i.e. <\/span>one that isn\u2019t accessible <\/b>to the public. For example, a database, a backend code (that programmers work with) or a page exclusively for subscribers. <\/span><\/p>\n

Error HTTP 401 (Unauthorized)<\/b><\/h3>\n

This one is like the 403 error, but it happens when there\u2019s an authentication failure (for example, on the form to access editing of a website). No page should ever show this error, unless it\u2019s for <\/span>internal use only<\/b>\u00a0and isn\u2019t public-facing (for example, a company\u2019s intranet). <\/span><\/p>\n

Error HTTP 400 (Bad Request)<\/b><\/h3>\n

This error appears when the page you\u2019re trying to access <\/span>isn\u2019t able to make sense of your request.<\/b> This usually happens because of a client error or a web address with an invalid format. <\/span><\/p>\n

Error HTTP 500 (Internal Server Error)<\/b><\/h3>\n

This refers to an <\/span>error with the internal server <\/b>you\u2019re trying to access. It could involve different issues related to that server, such as incorrect configuration or an overflow of requests. <\/span><\/p>\n

Error HTTP 503 (Service Unavailable)<\/b><\/h3>\n

The server can\u2019t respond to the browser\u2019s request because of <\/span>too much traffic or maintenance. <\/b>This is usually fixed after a few minutes, especially in the second case.<\/span><\/p>\n

Error HTTP 504 (Gateway Timeout)<\/b><\/h3>\n

This error means <\/span>the wait time to return the web page has run out. <\/b>This may be due to a server error (for example, it\u2019s gone offline) or because the web page has a code that never finishes executing and produces a loop.<\/span><\/p>\n

Error HTTP 509 (Bandwidth Limit Exceeded)<\/b><\/h3>\n

This error indicates that the web page you want to access <\/span>has exceeded its bandwidth. <\/b>This primarily happens on web pages with a cheap \u201chosting\u201d service that doesn\u2019t allow large volumes of traffic.<\/span><\/p>\n

So there you have it! May all your webpages load flawlessly and may you never encounter these numbers. And if you do, feel free to refer back here so you know why you’re disappointed.<\/p>\n
