Most Common Errors

Now we are defining about most common errors in web development.

Website errors are simply problems that come from a misconfigured server. These are usually software, but rarely, you might find the issue.  The most common are 401, 403, 404, 500, 502, 503, and 504 errors. The rest of the classes result in another website page, with status code information in the HTTP header

Most Common Errors

Most Common Website Errors and How to Fix Them:

  • Error 404 Page Not Found– The first and most popular server issue you have is a page not being found. If you are working with static HTML pages, this error means that you have not created the page you are trying to view
  • Error 401 Forbidden- This error is related to permissions. Every operating system has a way of managing acquire to files. If a user does not have access to these files, the operating system will give an error message when attempting to open the file. It also works with other features such as updating a file, deleting a file, or moving it.
  • Error 500 Internal Server Error- This is one of the most difficult errors to solve because it is so common. Anything could be an internal server issue. This usually involves sending a message to the browser saying that the website has encountered an unexpected error. Please try again later.
  • Error 400 Bad Request- This error is also common, but there are a few things you can check to make sure you get them resolved. This is often tied to the browser caching system and to the actual website. When you visit a webpage, your browser stores a copy of that webpage on your computer, so that you can access it later without sending another request.
  • Error 503 Service Unavailable- One of the major problems that can happen to your website is DDoS attack or denial of service. This is when someone floods your server with traffic that intercepts legitimate visitors from browsing.

Why are we facing Bad Gateway error?

What does this mean? A 502 Bad Gateway message indicates that one server received an invalid response from another. In short, you’ve connected to some sort of interim device (such as an edge server) that will receive all the bits needed to load the page. Server error codes indicate problems that are occurring on the backend of your website. They assume that the user has submitted a valid request, but something has prevented the server from responding.

How to Fix a 502 Bad Gateway Error

  • Reload the page.
  • Look for server connectivity issues.
  • Check for any DNS changes.
  • Sift through your logs.
  • Fix faulty firewall configurations.
  • Comb through your website’s code to find bugs.
  • Contact your host.
