+### Python Version Standardization
+
+**Important:** This project now uses **Python 3.11** across all services for consistency and performance.
+
+**Why Python 3.11?**
+- Better performance and memory efficiency
+- Compatibility with latest `ifcopenshell==0.8.0` wheels
+- Improved error messages and debugging
+- Long-term support and stability
+
+**All Dockerfiles use:** `FROM python:3.11-slim`

-### Common Issues
+### Common Issues and Solutions
+
+#### 🔴 Issue: "403 Forbidden" when accessing API
+
+**Cause:** Missing or incorrect API key
+
+**Solution:**
+1. Verify your `IFC_PIPELINE_API_KEY` in `.env` file
+2. In Swagger UI (http://localhost:8000/docs), click "Authorize" and enter the API key
+3. For curl requests, add header: `-H "X-API-Key: your-api-key-here"`
+
+#### 🔴 Issue: Queues showing "unhealthy (queue key not found)"
+
+**Cause:** This was the old behavior - queues now show "waiting (no jobs yet)" on first run
+
+**Solution:**
+- Update to latest version with improved health check messages
+- This is normal on first startup before any jobs are queued
+- Once you submit a job, the queue will initialize and show "healthy"
+
+#### 🔴 Issue: `ifcopenshell` installation fails or "No module named 'ifcopenshell'"
+
+**Cause:** ifcopenshell wheels not available for your platform or Python version mismatch
+
+**Solution:**
+1. Ensure you're using Python 3.11 (now standardized across all Dockerfiles)
+2. Verify `platform: linux/amd64` is set in docker-compose.yml for all Python services
+3. On Mac Apple Silicon: Enable Rosetta 2 in Docker Desktop settings
+4. Use pinned version: `ifcopenshell==0.8.0` (now in all requirements.txt)
+5. Rebuild images: `docker compose build --no-cache`
+
+#### 🔴 Issue: "network remotely-net not found" error
+
+**Cause:** External network for n8n-Remotely integration doesn't exist
+
+**Solution:**
+```bash
+# Option 1: Create the network
+docker network create remotely-net
+
+# Option 2: Comment out the network in docker-compose.yml
+# Remove or comment these lines under the n8n service:
+#   networks:
+#     - remotely-net
+# And remove the network definition at the bottom:
+#   remotely-net:
+#     name: remotely-net
+#     external: true
+```
+
+#### 🔴 Issue: Worker not processing jobs
 
-#### Worker not processing jobs
+**Cause:** Worker crashed, out of memory, or not running
+
+**Solution:**
 ```bash
 # Check worker logs
 docker compose logs ifcconvert-worker -f
 
 # Restart specific worker
 docker compose restart ifcconvert-worker
+
+# Check worker status in RQ Dashboard
+# Visit http://localhost:9181
 ```
 
-#### Out of memory
+#### 🔴 Issue: Out of memory errors
+
+**Cause:** Large IFC files or insufficient Docker resources
+
+**Solution:**
 ```bash
 # Check resource usage
 docker stats
 
-# Increase memory limits in docker-compose.yml
+# Increase memory limits in docker-compose.yml:
+# For heavy workers (ifcclash, ifcdiff, ifcpatch):
+deploy:
+  resources:
+    limits:
+      memory: 16G  # Increase from 12G
 ```
 
-#### Redis connection issues
+#### 🔴 Issue: Redis connection issues
+
+**Cause:** Redis service not running or connection refused
+
+**Solution:**
 ```bash
 # Check Redis status
 docker compose logs redis
 
 # Restart Redis
 docker compose restart redis
+
+# Verify Redis is accessible
+docker compose exec redis redis-cli ping
+# Should return: PONG
+```
+
+#### 🔴 Issue: Slow build times on Mac Apple Silicon
+
+**Cause:** Platform emulation (amd64 on arm64)
+
+**Solution:**
+- First build is slow (10-30 minutes) - this is expected
+- Subsequent builds use Docker cache and are faster
+- Consider using prebuilt images if available
+- Ensure Rosetta 2 is enabled in Docker Desktop
+
+#### 🔴 Issue: Sample IFC files not found
+
+**Cause:** Example files not present or incorrect path
+
+**Solution:**
+```bash
+# Verify sample files exist
+ls -la shared/examples/
+
+# Sample files should include:
+# - Building-Architecture.ifc
+# - Building-Hvac.ifc
+# - Building-Landscaping.ifc
+# - Building-Structural.ifc
+
+# Access them via the /examples volume mount in containers
+```
+
+#### 🔴 Issue: "Version mismatch" or dependency conflicts
+
+**Cause:** Outdated dependencies or mixed Python/package versions
+
+**Solution:**
+1. All Dockerfiles now use Python 3.11-slim
+2. All requirements.txt files pin ifcopenshell==0.8.0
+3. FastAPI/Pydantic versions are aligned across services
+4. Rebuild with: `docker compose build --no-cache`
+
+### Error Lookup Table
+
+| Error Message | Component | Quick Fix |
+|--------------|-----------|----------|
+| `403 Forbidden` | API Gateway | Add API key in Swagger UI or request headers |
+| `queue key not found` | RQ Workers | Normal on first run - submit a job to initialize |
+| `ifcopenshell not found` | Worker | Use Python 3.11 + platform: linux/amd64 |
+| `network not found` | Docker | Create network or remove from docker-compose.yml |
+| `Redis connection refused` | Redis | Check Redis logs and restart service |
+| `Out of memory` | Worker | Increase memory limits in docker-compose.yml |
+| `Worker not responding` | RQ Worker | Check logs and restart worker |
+| `Build timeout` | Docker | Increase Docker build resources |
+
+### Security Notes
+
+#### 🔒 Redis Security (CVE-2025-49844)
+
+**Critical:** Redis versions prior to 7.2.11 have a critical vulnerability allowing remote code execution.
+
+**Status:** ✅ Fixed in this repository
+- `docker-compose.yml` now uses `redis:7.2.11-alpine`
+- Redis port 6379 is bound to localhost only (not exposed publicly)
+- Redis is only accessible within the Docker network
+
+**Important:** 
+- Keep Redis internal-only (do not expose port 6379 to public internet)
+- Regularly update Redis to latest patch versions
+- Monitor DigitalOcean or security advisories for Redis updates
+
+**Current configuration (safe):**
+```yaml
+redis:
+  image: "redis:7.2.11-alpine"  # Patched version
+  ports:
+    - "6379:6379"  # Localhost only - safe for development
+```
+
+**For production:**
+```yaml
+redis:
+  image: "redis:7.2.11-alpine"
+  # Remove ports entirely - internal access only
+  networks:
+    - default
 ```
