NET::ERR_CERT_AUTHORITY_INVALID Error

NET::ERR_CERT_AUTHORITY_INVALID Error is an SSL error that can be fixed by the website owner. Though there are many reasons which may trigger this error, these three reasons are mainly responsible for this error.

  • SSL certificate is self-signed
  • SSL certificate has expired
  • SSL certificate is issued from non-trusted sources/certificate authority

SSL (Secure Socket Layer) certificates secure network communication made between a web browser and a website with encryption. Many times, compromised certificates may be used by hackers to target trusted sites, which may cause such errors. Hence, these error warnings should be taken seriously to prevent further damage.

If you are a website owner:

Being a website owner, NET::ERR_CERT_AUTHORITY_INVALID Error OR Your Connection Is Not Private specifies that the Chrome browser does not have trust in your SSL certificate, and it finds it suspicious.

You put in a lot of effort into attracting visitors to your website, and when such SSL errors pop up, it not only distracts visitors away from your site but also affects your business finances. Your site loses on to loyal customers, which in turn affects business sales too.

Suggestions:

  • Get an SSL certificate for your site from another trusted CA.
  • If you have a limited budget and are using a self-signed certificate issued by the server, they will not be trusted by browsers because CA does not issue them. Choose for any reputed brand and make the necessary changes to resolve the error.

If you are a website visitor
