To understand why the ERR_SSL_PINNED_KEY_NOT_IN_CERT_CHAIN error occurs, you'll need to know a bit about SSL certificates. SSL certificates are used to encrypt data that is transmitted between a website's server and a user's web browser. This helps keep sensitive information, such as login credentials and credit card numbers, safe from being intercepted by malicious third parties.
Each SSL certificate includes a public key that is used to encrypt data, and a private key that is used to decrypt it. The SSL certificate also includes information about the website's domain name and the organization that owns it. When you visit a website that uses SSL encryption, your web browser checks the SSL certificate presented by the website's server to verify that the website is legitimate and that the SSL certificate is valid.
