The Causes of the ERR_CERT_AUTHORITY_INVALID Mistake?
There is two Chief reasons you are getting this error:
Either the Certificate Authority that issued this site’s SSL certificate is not reliable, or The certification is self-signed.
Notice that invalid certificates similar to this are occasionally used by hackers to impersonate a reliable site, so that you shouldn”t dismiss this message. In any event, the best you are likely to be in a position to do is contact your site’s owner and inform them about the issue.
Sometimes there might be a way to get around that”your relationship isn’t personal” error in the event that you manually include the root certificate that the SSL certificate has been issued out of to your own system or browser’s confidence store. We’d just advise you do so in very specific situations (like you are an IT man and your business is employing a Personal CA).
However, our very best advice for customers would be to get the website owner and await them to repair it.

There is only one of two things which have happened to find this mistake, as we insured, possibly you self-signed your own SSL certificate or your Certificate Authority (CA) is no more trusted by the browsers. As we’ve seen with WoSign, StartCom and Symantec, with your CA distrusted isn’t unheard of.
In any event, unless you are a huge business working together with a CA to establish a Personal CA to your large community, our advice is to obtain an SSL certificate from a trusted authority.
