The error NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED is mainly caused by issues related to website SSL certificates. This error occurs when a website’s SSL certificate fails to comply with the Certificate Transparency policy enforced by browsers such as Chrome. When Chrome is unable to validate an SSL certificate on a website owing to a lack of transparency in the certificate’s issuing, this error appears. It is a security mechanism put in place to ensure that a trustworthy entity has issued the SSL certificate and that it has not been tampered with. There are n number of reasons for the error to be occured which are as follows:-

1) Certificate not added to transparency log

2) Incorrectly installed SSL certificate

3) Corrupted SSL certificate

4) Expired SSL Certificate

There are many different ways to fix the error which you need to  understand in detail and helps to solve it. Further I am attaching a resource for error solution:- https://cheapsslweb.com/blog/err-certificate-transparency-error-in-chrome/. Hope it helps!
