403 Forbidden error message

A 403 response means the website is refusing the request, so first determine whether the refusal follows Microsoft Edge, your Windows 11 device, your network, or only the affected website.

1. Isolate where the block occurs

For one affected site, test these combinations:

1. Open it in another browser on the same PC.
2. Open it on a phone connected to the same Wi-Fi.
3. Turn off Wi-Fi on the phone and try through mobile data.

Interpret the results:

• Fails only in Edge: Continue with the Edge steps below.
• Fails on every device using your Wi-Fi but works on mobile data: Restart the modem/router. If it continues, the website may be rejecting your network’s public IP address.
• Fails in every browser and on different networks: The website is probably denying access for an account, geographic, security, or server-side reason. Contact its support team.
• Fails only on the Windows PC: Check VPN, proxy, security software, and Windows networking.

Microsoft recommends comparing another browser and restarting the router to distinguish an Edge problem from a network or website problem.^1^

2. Remove data for only the affected site

Old authentication cookies can cause a site to reject a request. Deleting them signs you out of that site but avoids clearing every website’s data.

1. In Edge, open Settings and more (…) → Settings → Privacy, search, and services.
2. Select Cookies → See all cookies and site data.
3. Search for the affected website.
4. Expand its entry and select Delete.
5. Close all tabs for that site, reopen Edge, and sign in again.

The exact labels can vary slightly with Edge updates. Alternatively, press Ctrl+Shift+Delete, choose Cookies and other site data and Cached images and files, and clear them; this broader option may sign you out of other sites.^2^

3. Test Edge extensions

Enter edge://extensions in the address bar and temporarily turn off all extensions, particularly ad blockers, privacy tools, VPN extensions, and request-header modifiers. Reload the site.

If it works, re-enable the extensions one at a time until the 403 returns. Extensions can modify requests in ways that cause a website to reject them.^3^

4. Check privacy settings conditionally

If Tracking prevention is set to Strict, change it temporarily to Balanced:

1. Open Edge → Settings → Privacy, search, and services.
2. Under Tracking prevention, select Balanced.
3. Retry the website.

For a site you trust, you can instead open it, select the site-information icon beside the address, and turn off Tracking prevention for this site. Strict prevention can stop some websites from working or signing in correctly.^4^

5. Disconnect VPN or proxy temporarily

If Windows shows a VPN shield in the taskbar, open the Network, Volume, Battery panel, select VPN, and disconnect it temporarily.^5^

Also check Start → Settings → Network & internet → Proxy. If Use a proxy server or an unfamiliar setup script is enabled, turn it off temporarily and retry. On a work- or school-managed PC, do not change organization-controlled settings; contact the administrator instead.

6. Update or repair Edge only if the issue is Edge-specific

1. Open Edge → Settings and more (…) → Settings → About Microsoft Edge and install any available update.
2. If other browsers work but Edge still receives 403 errors:
   • Close Edge for every signed-in Windows user.
   • Open Start → Settings → Apps → Installed apps.
   • Find Microsoft Edge → Modify → Yes → Repair.

Repair should preserve browser data and settings. If Modify is unavailable, Edge may be organization-managed, in which case contact the administrator.^1^

If only one or two sites still fail after they work from another network, send the website operator the affected URL, approximate time, the displayed 403 text, and confirmation that another network works. Do not include passwords, session cookies, or account-sensitive screenshots.
