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