How to Fix Error Code INET_E_INVALID_REQUEST

  1. Reload the Page and Check Your Internet Connection

    Clearing cookies will sign you out of websites. Make sure you know your login credentials before proceeding.

    Running these commands as administrator modifies system network settings. These changes are safe but do require a system restart to take effect.

When to Call a Professional

This error is almost always resolvable without professional help. However, if the error persists on multiple browsers and devices on your network, the issue may be with your ISP or router firmware. In that case, contact your Internet Service Provider's technical support. If the error only appears on a corporate or school network, contact your IT department as network policies or a proxy server may be blocking certain HTTP request types.

Frequently Asked Questions

What does INET_E_INVALID_REQUEST mean in Microsoft Edge?
INET_E_INVALID_REQUEST means that Microsoft Edge attempted to send an HTTP request to a web server, but the request was considered invalid or improperly formed. This can happen due to corrupted cached data, misconfigured network settings, a misbehaving extension, or a bug in an older version of Edge.
Does INET_E_INVALID_REQUEST mean the website is down?
Not necessarily. While a server-side issue can trigger this error, it is far more often caused by something on your local browser or network. Try opening the same website in a different browser like Chrome or Firefox. If it loads fine there, the issue is specific to your Edge installation.
Will clearing my cache delete my passwords and bookmarks?
No. Clearing cached images and cookies does not delete your saved passwords or bookmarks in Edge. Your passwords are stored in the browser's password manager and your bookmarks in the Favorites section — both are unaffected by a cache clear. However, you will be logged out of websites that rely on cookies to keep you signed in.
Can a VPN cause the INET_E_INVALID_REQUEST error?
Yes. Some VPN services route traffic through proxy servers or modify HTTP headers in ways that can cause Edge to generate invalid requests. Temporarily disabling your VPN and reloading the page is a quick way to test if your VPN is the source of the problem.
Is INET_E_INVALID_REQUEST the same as a 400 Bad Request error?
They are related but not identical. A 400 Bad Request error is a server-side HTTP status code meaning the server rejected the request. INET_E_INVALID_REQUEST is an internal Edge error code that can appear before a request even reaches the server, often triggered by browser-level issues like corrupted cache, bad extensions, or network configuration problems.
