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