8 Most Common HTTP Error Codes With Their Meanings

 When you enter a URL address or click on a link to a site, the desired web page will usually be loaded on your device. Sometimes, though, something goes wrong and you get an HTTP Error Code.

There are many types of website errors, and each is assigned a three-digit HTTP status code. The HTTP Error codes that you are most likely to see are codes in the range 400-499, which indicates an error on the web browser user side, and codes in the range 500-599, which means there is a problem on the server side. Here are the most common mistakes you may encounter while browsing the internet and their meanings.

400: Bad Request

400 is a common error you get when the server can't understand a request from the browser, either because it wasn't sent properly or because it got corrupted along the way. The 400 error can be caused by a number of factors, including a bad internet connection, caching issues, or browser crashes. Check your connection and settings, clear your cache, open a different browser, and try again.

401: Authorization Required

The 401 status code, or Unauthorized error, means that the user trying to access the resource has not been authenticated or has not been authenticated properly. This means that the user must provide credentials to view protected resources. An example of a scenario where a 401 unauthorized error will be returned is if a user tries to access a resource protected by HTTP authentication. In this case, the user will receive a 401 response code until they provide a valid username and password to the web.v server

When you try to load a web page that you don't have permission to access, you will get a 403 error. Usually, getting this error means you have entered a URL or clicked on a link that leads to a page that has been set up with access permissions, meaning you must have an account or type other authorization to be able to access the page. Try going to the homepage of the website and getting your desired location from there, check to see if account registration is an option.

404: Not Found

The 404 error indicates that the server cannot find the page you are looking for. With this error, it's likely that the URL was entered incorrectly, so double-check the spelling, punctuation and suffixes (.com, .net, .org, etc.) of the domain name and try again.

405: Method Not Allowed

The 405 error is less common and easier to define than the others. Basically, a 405 error means that the server understands what the web browser is requesting, but refuses to fulfill the request. The 405 error can be caused by an error in the website code or an incorrect redirect.

500: Internal Server Error

500 is the most common server error, and like 400 it is generic code leading to an unspecified problem. Whenever a server encounters a difficulty that prevents it from fulfilling a request and the problem is not one that is described by other available server code, the server generates a 500 error. Try reloading the page, clearing cache, clearing cookies and restarting the browser.

502 Bad Gateways

A 502 status code, or Bad Gateway error, means that the server is a gateway or proxy server, and did not receive a valid response from the backend server that should have actually complied with the request. If the server in question is a reverse proxy server, such as a load balancer, here are a few things to check:

* Backend servers (where HTTP requests are forwarded) are healthy

* Correctly configured reverse proxy, with proper backend defined

* The network connection between the backend server and the reverse proxy server is healthy. If the servers can communicate on other ports, make sure the firewall is allowing traffic between them

* If your web application is configured to listen on a socket, make sure the socket is in the right location and has the right permissions

503: Service Unavailable

Error 503 indicates that the web server was unable to process the request. When you get a 503 error, it could mean the server is undergoing maintenance, or is oversubscribed. The best approach with a 503 error is to try again later. But usually the error occurs because:

* Poor network connection between servers

* Backend servers fulfilling requests are too slow, due to poor performance

* Gateway or proxy server timeout duration is too short

Conclusion

So once you are familiar and know the most common HTTP Error Codes and ways to solve these errors. You should have a good basis for troubleshooting any issues that may occur with your web server or application.
