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