ERR_BLOCKED_BY_CLIENT

How to Fix “ERR_BLOCKED_BY_CLIENT”

Browser & Proxy Error 📄 Chrome, Edge, Brave
⚡ Quick answer

ERR_BLOCKED_BY_CLIENT means a browser extension — almost always an ad blocker or content blocker — intercepted and blocked the request before it was sent. This is not a network error; the block happened entirely within your browser.

First, check if your internet is working and what your current IP address is:

What Causes the “ERR_BLOCKED_BY_CLIENT” Error?

An ad blocker, privacy extension, or firewall extension has a rule matching the URL you're trying to load and blocked it. This commonly affects ads, analytics scripts, and tracking pixels, but can incorrectly block legitimate page resources, causing parts of a page (or the whole page) to fail.

How to Fix It — 5 Methods

1 Disable Your Ad Blocker for This Site ▶

Click your ad blocker's icon in the Chrome toolbar and look for a "Pause on this site," "Whitelist," or "Disable for this domain" option. Reload the page. If it now loads, the ad blocker was blocking a resource the page needs to function. Add the site to your whitelist permanently if you trust it.

2 Test in Incognito Mode ▶

Press Ctrl+Shift+N to open incognito. Extensions are disabled by default in incognito. If the resource loads in incognito, confirm which extension is responsible by going to chrome://extensions and disabling them one by one in normal mode.

3 Check Your Extensions ▶

Go to chrome://extensions and temporarily disable all extensions. Reload the page. If it works, re-enable extensions one by one to identify the culprit. Common offenders: uBlock Origin, AdBlock Plus, Privacy Badger, Ghostery, and any VPN or firewall extensions.

4 Update Your Ad Blocker Filter Lists ▶

Outdated filter lists sometimes incorrectly block legitimate resources. In uBlock Origin: click the extension → open the dashboard → Filter lists → Update now. In AdBlock: Options → Filter lists → Update. Old lists may have rules that match the wrong URLs.

5 Check Windows Firewall or Parental Controls ▶

If no extensions are blocking the request, check Windows Firewall rules or parental control software. Some security software blocks specific URLs or domains system-wide, which Chrome reports as ERR_BLOCKED_BY_CLIENT since the block happened at the OS level.

Frequently Asked Questions

Is this error ever caused by the website itself?
Rarely — websites can use the Permissions Policy header to block certain browser features (camera, microphone, etc.) but this doesn't cause ERR_BLOCKED_BY_CLIENT for page loads. The error is almost always an extension or client-side firewall.
Only specific images or scripts are blocked — is that normal?
Yes, this is how ad blockers are supposed to work — they block specific tracking scripts and ads. If only ads and analytics are blocked and the rest of the page loads fine, your ad blocker is working correctly.
Can I see what specifically was blocked?
Yes — open Chrome DevTools (F12) → Network tab → reload the page → filter by "Blocked." You'll see all blocked requests and which extension blocked them. This helps identify whether legitimate resources are being incorrectly blocked.
