I am experiencing issues with the SSL certificate for my subdomain admin.domaine.com. Despite following the standard procedures to issue and install the SSL certificate, I continue to receive the error “NET::ERR_CERT_AUTHORITY_INVALID” when accessing the subdomain.
When accessing the subdomain, you are continuously receiving the error “NET::ERR_CERT_AUTHORITY_INVALID” even while following the procedure of installing the SSL certificate. It occurs when your browser fails to validate the authenticity of the SSL certificate that secures your website. There are different reasons for the error to have occurred, some are as follows:-
SSL Certificate that is Self-signed
Outdated SSL Certificates
The Certificate was installed incorrectly
Certifying Authority that needs to be More Reliable
Cache from an Expired Browser
There are also different ways to fix the error. For a more detailed understanding, you can check out the reference article at Certera. com
