+# Task Runners Health Check Fix
+
+**Date:** 2026-02-01 13:20
+**Context:** Fixed unhealthy status on n8n task-runners container
+
+## Problem
+
+The `task-runners-uk0o04o0g84s4sc80kkoooc0` container was showing as unhealthy with 60,395+ consecutive failures.
+
+**Root Cause:** Health check was configured to hit `/` but the actual health endpoint is `/healthz`
+
+| Configured | Actual Endpoint |
+|------------|-----------------|
+| `http://127.0.0.1:5680/` | Returns 404 |
+| `http://127.0.0.1:5680/healthz` | Returns `{"status":"ok"}` |
+
+## Solution
+
+Updated Coolify's docker-compose configuration for the n8n service:
+
+```bash
+docker exec coolify php artisan tinker --execute="
+use App\Models\Service;
+\$service = Service::find(4);
+\$compose = \$service->docker_compose_raw;
+\$compose = str_replace(
+    \"'wget -qO- http://127.0.0.1:5680/'\",
+    \"'wget -qO- http://127.0.0.1:5680/healthz'\",
+    \$compose
+);
+\$service->docker_compose_raw = \$compose;
+\$service->save();
+"
+```
+
+Then restarted the service:
+```bash
+docker exec coolify php artisan tinker --execute="
+use App\Models\Service;
+use App\Actions\Service\StopService;
+use App\Actions\Service\StartService;
+\$service = Service::find(4);
+StopService::run(\$service);
+StartService::run(\$service);
+"
+```
+
+## Result
+
+- Container now shows as **healthy**
+- Health check correctly hitting `/healthz` endpoint
