If you want https://artgoodman.com/ to work – even if it’s only to send an HTTP redirect – you’ll need a certificate for artgoodman.com.
It looks like you issued two certificates, each for the names artgoodman.com and *.artgoodman.com, in recent weeks. (crt.sh lists them twice due to Certificate Transparency stuff.)
If you still have the keys, great.
If you can just put the /etc/letsencrypt/ directory back in place, perfect. (If you were using a different ACME client, restoring its configuration directory would probably also be perfect.)
It might be easier to just issue a new certificate, especially if your new server already has other certificates set up. In particular, issuing a new certificate tests that all of the configuration details are correct and that renewing it will (probably) work in the future.
