Chrome is in the process of removing Symantec's certificates and infrastructure. The goal of this update is to uphold users’ security and privacy when browsing the web. Google will move to a new, independently-operated Managed Partner Infrastructure until Symantec can redesign its infrastructure to adhere to industry standards.
Chrome 66
Starting with Chrome 66, Chrome removed trust in Symantec-issued certificates issued prior to June 1, 2016. Chrome 66 was scheduled to be released to Chrome Beta users on March 15, 2018 and to Chrome Stable users around April 17, 2018.
You may have received a notice stating that site operators with a certificate issued by a Symantec CA prior to June 1, 2016, then prior to the release of Chrome 66, will need to replace the existing certificate with a new certificate from any Certificate Authority trusted by Chrome.
