If you see the following error on the right hand side of your cPanel then the SSL for your domain isn't auto installed. This maybe due because the domain is so new our system hasn't yet installed your free SSL.
First click the Spanner on the right hand side or click the "SSL/TLS Status" icon.
Next click "Run AutoSSL" this task may take up to an hour to complete however generally completes within 5 minutes.
Once complete all padlocks will show green. If you have a domain which isn't hosted within your cPanel account you can exclude it from AutoSSL.
