What is the NET::ERR_CERT_SYMANTEC_LEGACY Error?

The NET::ERR_CERT_SYMANTEC_LEGACY error is a warning message that pops up in Google Chrome. The warning message or the error indicates that the browser (in this case, mainly Chrome) no longer trusts SSL certs issued by Symantec prior to June 1, 2016.

This distrust arose due to concerns over Symantec’s adherence to industry-standard practices for certificate issuance. Following the sale of Symantec’s CA business to DigiCert, Symantec no longer issues SSL certificates.
