Version 54.0.2840.100 (64-bit)
Linux openSUSE 42.1.

Your connection is not private – NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED
Most of the reports here are to running an old and out-of-date Chromium v. 53 on Linux distros. Specifically this error will happen when using out of date Chrome/Chromium to go to secure websites who use SSL security certificates issued by Symantec or Symantec associated groups, including GeoTrust, Thawte, and VeriSign.

zypper se -s chromium-ffmpeg

We reupgraded to v.56 and now everything works.
