Quote:If you’ve been on the Internet for a while, chances are good you’ve encountered a variety of errors. While avoiding errors altogether is not possible, it does help to understand what those errors mean and some basic steps for resolving them.

Common Types of Online Errors

Most online errors are accompanied by an HTTP status code. Commonly, you’ll see a 4XX or a 5XX error—a 4 or 5 followed by two additional digits, like 404.

Both 4XX and 5XX are errors, but they have a significant difference. 4XX errors are Client Errors while 5XX are Server Errors. If you see a 4XX error, chances are it’s something you can fix.

5XX errors are Server Errors, which means that you’ve done nothing wrong, but the server you’re trying to access is acting up. Regardless of the error, you can perform a few steps that might help solve the problem.

We’ve listed the most common online errors below and also mentioned a couple of helpful solutions for each error. You can’t solve all online errors; some happen on the server end, and there’s not much you can do about them. Still, it doesn’t hurt to try.
