# ERR_CONNECTION_TIMED_OUT on WordPress

> A PHP worker pool exhausted by a slow plugin or a runaway cron job accepts no new connections, so the site times out while the server itself is fine.

## Why it happens on WordPress

 A PHP worker pool exhausted by a slow plugin or a runaway cron job accepts no new connections, so the site times out while the server itself is fine.

## The fix on WordPress

 Disable wp-cron's default request-driven mode and run it from system cron, then check PHP-FPM's pm.max_children against actual usage. Deactivate recently added plugins one at a time to find the blocker.

## If that didn't fix it

 WordPress has its own failure mode, but ERR_CONNECTION_TIMED_OUT has a wider set of causes. The most common one overall is: The origin server is down or the web server process has stopped.

 Check the service is running and listening on the expected port, then restart it and confirm from outside the network.

## Check your own domain

 An uptime probe from outside your network tells you whether the server is unreachable for everyone or only from where you are sitting — which is the first fork in every timeout diagnosis.
