A self-signed certificate encrypts traffic but is not signed by a certificate authority that browsers normally trust. Because the browser cannot build a trusted chain to a recognized authority, visitors receive a certificate warning.
cPanel documentation recommends using a certificate obtained through a certificate authority rather than relying on self-signed certificates for public services.
Do not train visitors to bypass certificate warnings on a public website. Replace an unintended self-signed certificate with a trusted certificate that covers the correct hostname.
