TLS-SNI-01 validation is reaching end-of-life

Hello... Looking forward to some help.

No matter what I do, I cant renew using http. It ALWAYS goes to tls-sni

I am on Ubuntu 16.
Certbot 0.28

I see NO references to tls-sni in my conf files anywhere.
I have tried forcing the preferred challenge to HTTP-01.. but it always attempts to use tls-sni

WORKS:
certbot --dry-run

FAILS:
certbot --force-renew

Select the appropriate numbers separated by commas and/or spaces, or leave input

Renewing an existing certificate

TLS-SNI-01 is deprecated, and will stop working soon.
Waiting for verification...
Cleaning up challenges
Deploying Certificate to VirtualHost /etc/apache2/sites-enabled/000-default-le-ssconf

I have scoured the /etc/letsencrypt folder for ANY references to tls-sni

grep -iRl "tls" ./

(no hits)

I have tried adding HTTP as a preferred challenge both in the client.ini and the domain renewal file itself... again, NO change in behavior.. it continues using tls-sni

welp??
