How to Setup WHM and CPANL so clients will be redirected to a valid SSL Certificate when logging in.

How to Setup WHM and CPANL so clients will be redirected to a valid SSL Certificate when logging in.

Instructions based on WHM v11.15.0

1) Purchase / Install the Certificate for your fully qualified domain (ie: server.domain.com)

SSL / TLS >> Install a SSL Certificate and Setup the Domain

2) Test your new CERT

https://server.domain.com/
should resolve and the cert should function properly before moving forward.

https://server.domain.com:2087/
should be giving you an invalid certificate error

3) Install the CERT for the WHM and CPANEL Service (this is the step you don't think about!!)

Service Configuration >> Manage Service SSL Certificates
> Select "Install New Certificate" for the "cPanel/WHM/Webmail Service"
> Select Domain this CRT is for "Browse"
> Pick the full server cert you installed "server.domain.com"
> Press "Submit" to install

4) Test your Service Certificate

https://server.domain.com:2087/

should now be working !! WHOOOO

Note: In "WHM >> Server Configuration >> Tweak Settings", under the "Redirection" tab, you can set the "SSL redirect destination" option to

"SSL Certificate Name"


This will ensure the request is redirected to the SSL Certificate hostname.
