Elastic App Search web crawler

Failed to fetch robots.txt: SSL certificate chain is invalid [unable to find valid certification path to requested target]. Make sure your SSL certificate chain is correct. For self-signed certificates or certificates signed with unknown certificate authorities, you can add your signing certificate to Enterprise Search Crawler configuration. Alternatively, you can disable SSL certificate validation (non-production environments only).
