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