Fwd: authentication fail

I am currently unable to collect mail from a mail provider.  This has
worked in the past.  The line in the logs:
   fetchmail: imap.themessagingco.com.au: WARNING: server offered STARTTLS
but sslproto '' given.
looks pretty suspicious.

OS: Fedora 40 Linux
Package: fetchmail-6.4.38-1.fc40.x86_64
MDA: procmail, though it never gets called
Command line: just "fetchmail", however .fetchmailrc is:

poll imap.themessagingco.com.au protocol IMAP port 993
  auth password
  user "mpope" password "*********"
  ssl sslproto tls1.2+ sslcertck
  mda "/usr/bin/procmail -o -d mpope"

LC_ALL=C fetchmail -V: attached as fet1.log
LC_ALL=C fetchmail --nodetach -vvv --nosyslog: attached as fet2.log

Cheers,
Mike Pope
