Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
It produced this output:
AutoSSL did not renew the certificate for “rootsofaussierock.com”. You must take action to keep this site secure.

I have moved these two sites from a shared hosting to our own server and not sure how to respibd to these requests.
Do you have any other info you can share? Is there some sort of error log or something?
Because the message "AutoSSL did not renew ..." sounds like AutoSSL was expecting to have an existing cert and renew it. But, the only certs I see in your history were from cPanel, Inc and not Let's Encrypt. (link here).
Yes, autoSSL in cPanel can support Let's Encrypt but I don't know how to install those products for that purpose. You might get best help from the cPanel forum (link here) on how to set it up. If nothing else, they can instruct you how to get more detailed logs for debugging.
If you can get more info that points to a Let's Encrypt problem we can give better advice
ADD:
But, if you don't need to use AutoSSL and cPanel there are many other ACME clients to get Let's Encrypt certs. See below
BTW As I have a few sites on my linux apache2 home server and getting more, is there an option that will make all sites ssl, or is it a one by one task?
Setting up new domains and related server config is usually one-by-one task. The SSL certs are just one of those steps.
I don't see HTTPS working on either domain in your first post. I checked from various points around the globe including one in Melbourne. Port 443 looks blocked possibly by a firewall. I also don't see any fresh cert in the public logs although sometimes there is a delay before appearing there.
