If that was you under the other username, then yep you forgot to add the new cipher qualifier.
I thought I’d made the required change clear enough in the Linux Tips post
# Generate new p12 (Acme LE is valid until 2025)
openssl pkcs12 -export -out my-fdqn-tld.p12 \
-certpbe AES-256-CBC -keypbe AES-256-CBC -macalg SHA256 \
-inkey my-fqdn-tld.key -in my-fqdn-tld.crt \
-certfile CertAuth.crt \
-password pass:PASSWORD_HERE
It was like 4-almost 5am here. (sorry if I was fuzzy/terse)
After that — PMS restart is required to load the new cert.
