## Symptoms

- * Users sometimes get 504 errors. In some cases, the page loads after a refresh, and some page elements may load while others fail.
* Users always get a 504 error. No part of the page loads, and every request times out.

## Cause

* The origin server does not respond within the allowed timeout because of slow or overloaded resources.
* One or more of the three WAF egress IP addresses cannot reach the origin server due to firewall, ACL, or network restrictions.
