**Solution**:
- Verify credentials: default is `admin`/`admin`
- Check if API is enabled in `system.properties`
- Use proper authentication header:
  ```bash
  curl -u admin:admin ...
  # or
  curl -H "Authorization: Basic YWRtaW46YWRtaW4=" ...
  ```

#### Issue: Large bulk imports timing out

**Solution**:
- Split large files into smaller batches (e.g., 10,000 docs per file)
- Increase timeout in `system.properties`:
