Certificate is valid! What did you expect to see? According to RFC 5280, Section 4.2.1.10, the Name Constraints extension is permitted only in CA certificates, not in end-entity certificates. Cryptography fails to verify the certificate and throws the relevant error according to RFC5280: Certific...
