Thanks for the tip. I will dig into this a little and see if I can convert from RSA to the ecliptic curve cryptography.

Not so difficult, if you use let's encrypt
Run certbot with force renew and ecdsa parameter. I don't know the exact syntax
Thank you for tip. It was relatively straight forward and simple once I found the guide based on your lead. I managed to clean some things up in the process.
Something like this .. you may need to specify the curve depending on your version of certbot -->
certbot renew --dry-run --key-type ecdsa --cert-name example.com --force-renewal
Here's the reference to help anyone else taking the same path -->
