We are aware that s small subset of users of the Chromium web browser may receive the following error when trying to access websites and control panels via HTTPS that use the *.niner.net certificate:
Your connection is not private
Attackers might be trying to steal your information from cp31.niner.net (for example, passwords, messages or credit cards). NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED
(cp31.niner.net will be replaced by whatever domain you are trying to access.)
If you click the “ADVANCED” link you will see the following additional information:
The server presented a certificate that was not publicly disclosed using the Certificate Transparency policy. This is a requirement for some certificates, to ensure that they are trustworthy and protect against attackers.
This is a bug in Google Chromium, not a problem with our certificate.
Until Google fixes this bug we recommend using a better web browser (e.g., Firefox), or clicking the “Proceed to cp31.niner.net (unsafe)” link that is revealed when you click “ADVANCED” as described above. Clicking the “unsafe” link is indeed safe in this case. Even very big and very busy websites — such as Yahoo and Flickr for example — are currently affected by this bug.
