[GTALUG] Certificate Error On Chrome

[Michael Galea]

I went to pay my cell providers bill via Chromium on Debian and it threw 
a "Site not secure" error at me.  That was odd as I had paid at the same 
site many times before.

I reported the problem to the cell provider's customer support line, not 
really expecting much.  To my surprise they requested screenshots, and I 
provided them.

The tech came back and replied, "I have seen this error before. Click on 
“ADVANCED” and you should then have an option to proceed to website and 
this should resolve the issue". :-)

I replied that I would try paying by another means thanks, and that if I 
was seeing the site warning, others were likely to as well..

Google was reporting "Certificate Error : There are issues with the 
site's certificate chain net::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED)." 
Apparently, Google started following a 2013 protocol that detects 
fraudulent certificates, and the cell providers certificate vendor does 
not support it.

Has anyone else seen these sorts of certificate problems, and why now?
