CRE-2025-0054 Medium Impact: 7/10 Mitigation: 5/10	NGINX upstream connection timeout	NGINX reports an upstream timeout error when it cannot establish or maintain a connection to backend services within the configured timeout threshold. This occurs when backend services are unresponsive, overloaded, or when the timeout values are set too low for normal operation conditions. The error indicates that NGINX attempted to proxy a request to an upstream server, but the connection or read operation timed out before completion.
