updating Public CA certificate on 11.1

[GayathriPulla]

Hi All, 
Is there any article how to update the Public ca certificate and server certificate for NW server console. I am not able to find any article for 11.1

We should  include Subject Alternative Name into the certificate when we generate the same. 

For Chrome 58 and later, only the subjectAlternativeName extension, not commonName, is used to match the domain name and site certificate. The certificate subject alternative name can be a domain name or IP address.
