Jerry, "timeout" is suspicious and hints to network issues.

The usual drills is: no logs, no support.

And guess what, fetchmail 6.4.1 does work for me, without or with
--sslproto auto, I can connect to mail.twc.com.
This is on FreeBSD 12.0 RELEASE (OpenSSL 1.1.1a-freebsd  20 Nov 2018)
and Fedora 30 (OpenSSL 1.1.1d FIPS  10 Sep 2019)
