net::ERR_BLOCKED_BY_CLIENT

The visitor's ad blocker or privacy extension stopped the request.

For visitors with a blocker, anything that script did is missing; if your page waits on it, more than that.

Why it happens

• An extension (uBlock Origin, AdBlock, Ghostery, Privacy Badger) matched the URL: analytics, ads and trackers most often.
• Paths with words like ads, track or analytics get blocked even when they are your own features.
• It never happens in a browser with no extensions, which is how Broken Here's checker runs.

How to fix it

1. Nothing to fix for trackers: make the page work without them.
2. If one of your own features is blocked, rename paths and files that look like ads or tracking.
3. Never let the rest of the page depend on a script that may be blocked.

Whose problem it is

Usually the visitor's own browser or network.
