Apache HTTP ServerApache HTTP Server metrics correlate with this issue and help confirm diagnosis

How to detect:

Traefik forwards requests to Apache backends but timeouts occur, even though the Apache server can independently handle 10x the traffic volume being sent through Traefik

Recommended action:

Check Traefik timeout configurations (forwardingTimeouts, responseHeaderTimeout, idleTimeout) in static and dynamic configuration. Verify network latency between Traefik and Apache. Review Apache's KeepAlive and timeout settings for compatibility with Traefik's connection pooling. Monitor connection states and request durations to identify bottlenecks.
