Clear Browser Data and Disable Extensions

Resolves issues caused by corrupted site cookies, conflicting browser extensions, or IP blocks triggered by active VPNs.

Web browsers store cookies and cached data that can sometimes become corrupted, causing secure portals like Microsoft Support to block your request. Additionally, privacy extensions and VPNs may mask your connection in a way that triggers Microsoft's automated security filters.

1
Open a Private Window

Launch your web browser and open a new Incognito or Private browsing window. Try accessing the Microsoft Support chat again.

2
Clear Cache and Cookies

If the private window fails, go to your browser settings, locate the privacy or history section, and clear your cache and cookies for all time.

3
Disable VPN and Ad-blockers

Temporarily turn off any active VPN connections on your device. Next, disable ad-blockers or tracking prevention extensions in your browser settings.

4
Refresh the Page

Reload the Microsoft Customer Support page and click the button to initiate the chat.

Frequently Asked Questions

Why is Microsoft blocking my support request?

A 'Request Blocked' error is usually an automated security measure. It triggers if your IP address is flagged for too many failed login attempts, if you are using a VPN that Microsoft's firewall distrusts, or if corrupted browser cookies conflict with the site's session verification.

How long does a temporary Microsoft IP block last?

If Microsoft temporarily blocks your IP address due to suspicious activity or repeated login failures, the restriction typically lasts between 12 to 24 hours. After this period, the block usually lifts automatically.

Can a browser extension cause the 'Request Blocked' error?

Yes. Strict ad-blockers, tracking prevention extensions, and privacy add-ons can block scripts necessary for the Microsoft support chat to load. Disabling these extensions temporarily or using an Incognito window often bypasses the error.
