That was only an EXAMPLE.
Please use the same certbot command as you always use but add "--preferred-chain" part at the end.

Show it here to verify syntax.

Too funny!
I misspelled preferred as preffered.
And that's how bugs get into programs...
Use one "f" and two "r" (well three in total)

That guide has many manual items which prevents automated renewal. Are you sure you don't just want to follow the official guide at Installing a LetsEncrypt SSL Certificate - Zimbra :: Tech Center ?

Can you try to manually add (with a text editor) the ISRG Root X1 certificate to /opt/zimbra/common/lib/perl5/Mozilla/CA/cacert.pem, and try the last step again?
