--- Testing Instructions ---
1. Test Captcha Implementation:
docker exec crowdsec cscli decisions add --ip YOUR_IP --type captcha -d 1h
(Replace YOUR_IP with your actual IP address)
2. Verify decisions:
docker exec -it crowdsec cscli decisions list
3. Test security by accessing DOMAIN_NAME/.env (should return 403)
(Replace DOMAIN_NAME with the domain you entered)
--- Troubleshooting ---
1. If encountering 403 errors:
- Check Traefik logs: docker compose logs traefik -f
- Verify CrowdSec logs: docker compose logs crowdsec
2. For plugin errors:
- Verify http notifications are commented out in profiles.yaml
- Restart services: docker compose restart traefik crowdsec
3. For Captcha issues:
- Ensure Turnstile is configured in non-interactive mode
- Verify captcha.html configuration
- Check container network connectivity
Useful Commands:
- View Traefik logs: docker compose logs traefik -f
- View CrowdSec logs: docker compose logs crowdsec
- List decisions: docker exec -it crowdsec cscli decisions list
- Check metrics: curl http://localhost:6060/metrics | grep appsec
