My domain is healthpulses.com. I am using Hostgator as a hosting service provider. I have already uploaded the certificate generated from Letsencrypt, but the security option is not updated. Hostgator people say CA Bundle files are missing. So can anyone guide me how the CA Bundle files are generated because during following the process to generate the certificate through ZeroSSL, I have not seen any file called CA Bundle, there was only the private key and CRT.
