Obtaining certificate chain for hanoi.duphong.net, one moment while we download the hanoi.duphong.net certificate and related intermediate certificates...
Revocation check via OCSP and CRL for hanoi.duphong.net failed
Sorry, the request for hanoi.duphong.net could not be completed...
We could not load the certificate for hanoi.duphong.net, it might not exist or we could not reach the server, complete the TLS handshake, etc.
Revoked certificates can't and should not be trusted, these certificate will cause errors like "NET::ERR_CERT_REVOKED" in browsers and expose a security risk.
