n8n errors / Config

All executions stuck in "Queued" / "Starting soon" and never executed

platform: n8n / category: Config

Cause

Workers disconnected from Redis (or never started) while holding job locks, leaving queued executions in a stale locked state that new workers cannot claim.

Fix

Set QUEUE_HEALTH_CHECK_ACTIVE=true to detect worker disconnects. Restart worker containers to release stale Redis locks; jobs requeue automatically. Ensure every main/webhook/worker container shares EXECUTIONS_MODE=queue and identical Redis vars. Avoid OFFLOAD_MANUAL_EXECUTIONS_TO_WORKERS=true if you stop executions manually.
