What Causes 403 Forbidden Errors

Different web servers report 403 Forbidden errors in different ways, the majority of which we’ve listed below (see the Common 403 Error Messages section). Occasionally a website owner will customize the site’s error, but that’s not too common. These errors are caused by issues where you’re trying to access something that you don’t have permission for. The error is essentially saying “Go away and don’t come back here” because the server’s access permissions indicate that you’re truly not allowed access or the permissions are actually improperly set up and you’re being denied access when you shouldn’t be.

How to Fix the 403 Forbidden Error

Different website designs can produce 403 errors that might make them seem different from site to site but, overall, they are pretty much the same thing. Often, there’s not much you can do because the error typically stems from the development and design of the site. Occasionally, though, it could be a problem on your end. Here are a few things to try so you can confirm it’s not your side of the connection causing the problem.

How the 403 Error Can Appear on Different Sites

These are the most common incarnations of 403 Forbidden errors: If you operate the website in question, and you want to prevent 403 errors in these cases, enable directory browsing in your web server software. Typically, a website produces a 401 Unauthorized error when special permission is required, but sometimes a 403 Forbidden is used instead. Most sites have support-based accounts on social networking sites, making it really easy to get a hold of them. Some even have support email addresses and telephone numbers. It’s possible that your public IP address, or your entire ISP, has been added to a blocklist, a situation that could produce this error, usually on all pages on one or more sites. If that’s the case, and your ISP can’t help you, connecting to a VPN server from a region of the world that does permit access, should be enough to resolve the error.

The error displays inside the browser window, just as web pages do, and like all errors of this type, it can be seen in any browser on any operating system. These errors, when received while opening links via Microsoft Office programs, generate the message Unable to open [url]. Cannot download the information you requested inside the Office software. Windows Update might also report an HTTP 403 error but it will display as error code 0x80244018 or with the following message: WU_E_PT_HTTP_STATUS_FORBIDDEN.
