generated: '2026-09-06' method: probed source: live DNS/TLS/HTTP probes of apis.yml + OpenAPI hosts note: >- www.accropeutics.com negotiates TLSv1.3 but serves an INCOMPLETE certificate chain: the origin presents only the leaf (CN=accropeutics.com, issued by Certum Domain Validation CA SHA2) and omits the intermediate, so `openssl s_client` returns verify code 21, "unable to verify the first certificate". Ordinary browsers recover via AIA fetching; strict clients — curl without -k, Python urllib, and most server-side HTTP libraries — fail the handshake outright. The apex publishes SPF but no DMARC record, no CAA records, and the accropeutics.com zone is not DNSSEC-signed. hosts: - host: www.accropeutics.com https: true tls_cert_error: '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1082)' hsts: null domains: - domain: accropeutics.com dnssec: false caa: [] spf: true dmarc: false
