post net::ERR_CERT_AUTHORITY_INVALID code example

Example: Failed to load resource: net::ERR_CERT_AUTHORITY_INVALID

There’s one of two things that have happened to get this error, as we covered,
either you self-signed your SSL certificate or your Certificate Authority (CA)
is no longer trusted by the browsers. As we have seen with WoSign, StartCom 
and Symantec, having your CA distrusted is not unheard of.

Either way, unless you’re a large enterprise working alongside a CA to set up
a Private CA for your massive network, our advice is to purchase an SSL 
certificate from a trusted authority.
