Internet privacy refers to privacy rights that an individual has while connected to the internet concerning their data. It can be protocols for privacy protection, privacy statements on websites, data sharing controls, etc. So to keep user data secure and verify the authenticity of the website, all websites that ask for any personal information from users require an SSL Certificate. Comes with it ERR_CERT_AUTHORITY_INVALID error. We will deal with it in this article.

It enables websites to move from HTTP to HTTPS, which is secure. A CA is a trusted third party that generates SSL certificates. Once you issue the certificate, it needs to be installed and activated on the website’s origin server.

It is necessary because, without SSL encryption, all operations that you perform on the web page may be intercepted and used by a third party and even misused by hackers.

If you face an ERR_CERT_AUTHORITY_INVALID error, it is a sign that the browser does not trust your SSL certificate. Unfortunately, this means that the visitors accessing your website will also face this same error, affecting your revenue and reputation.

Reasons For The Error

There can be two possible reasons:

  • The certificate has expired: Check the expiration date (validity) of your certificate, and if it is expired, you have to renew it. 
  • The certificate is self-signed: A self-signed SSL certificate is created by generating a public-private key pairing and including all required information. An outside authority does not verify it.
