Obtaining certificate chain for em16.klmedien.de, one moment while we download the em16.klmedien.de certificate and related intermediate certificates...
Revocation check via OCSP and CRL for em16.klmedien.de failed
Sorry, the request for em16.klmedien.de could not be completed...
We could not load the certificate for em16.klmedien.de, 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.
