Error NET::ERR_CERT_AUTHORITY_INVALID

[leocardo]

I was facing the same problem, and tried a lot of "solutions" in order to solve it.

Finally I found a procedure that works for my particular case, check that DNS servers are the DNS provided by the Internet Service Provider, reconfigure it, reconnect PC in order to refresh DNS and try it, should works... after that reconfigure with DNS that you prefer...

A domain should resolve to a IP.
And a certificate needs valid X509v3 Subject Alternative Name (SAN).
If not, that certificate will not work.
And this was defined 5 years ago!

It is the job of a web developer/IT pro to know this. Not in your knowledge box!?, keep on learning

I f you are testing software on a local webserver, set a IP from your LAN, add IP and domain to your router or local DNS server, that could resolve the cert issue.
