I think the problem might be partly caused because the ongarinbloom.com domain (without the www) has two A records - one for the new server address and one for the old one. This seems to have confused the automatic certificate registration system.
If you delete the one for the old server (22.214.171.124) and leave only the one for the new (126.96.36.199) then this would be a good step in the right direction.
I will also have a look to see if I can manually get the certificate working.
Many thanks Joe. Have deleted so just have the new ip address for @ and www now.
