3. Check crawler logs: `logs/fess-crawler.log`
4. Manually trigger re-indexing:
   - Admin > Scheduler
   - Run "Default Crawler" job

#### Issue: Authentication errors on API calls

**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

    freshness.incrementAndGet();
    return proxy;

* Audit logs might impact the API server performance and the latency of large request and response calls. The issue is observed under the following conditions: if `AdvancedAuditing` feature gate is enabled, which is the default case, if audit logging uses the log backend in JSON format, or if the audit policy records large API calls for requests or responses.
