[syslog-ng] CentOS syslog-ng using tls won't start via systemd but runs fine manually (sort of)

I'm been trying to figure this out for several days now.
I have Centos 7 installed on two servers and I want to use syslog-ng to
send logs between them securely using TLS.
On both I installed syslog-ng 3.5 using this method:
https://www.syslog-ng.com/community/b/blog/posts/installing-latest-syslog-ng-on-rhel-and-other-rpm-distributions
I have been following these methods as a starting point to set up:
https://www.nineproductions.com/syslog-ng-with-tls-setup-for-centralized-logging/
https://www.linux.com/blog/tls-encryption-and-mutual-authentication-using-syslog-ng-open-source-edition
https://www.flyn.org/notes/logging/index.html
On the receiving server, I have syslog-ng with the following config
file:
----------------------------------------------------------
@version:3.5
@include "scl.conf"
# syslog-ng configuration file.
#
# This should behave pretty much like the original syslog on RedHat. But
# it could be configured a lot smarter.
#
# See syslog-ng(8) and syslog-ng.conf(5) for more information.
#
# Note: it also sources additional configuration files (*.conf)
# located in /etc/syslog-ng/conf.d/
options {
flush_lines (0);
time_reopen (10);
# log_fifo_size (1000);
# chain_hostnames (off);
use_dns (no);
use_fqdn (no);
create_dirs (1);
keep_hostname (yes);
};
source s_sys {
system();
internal();
# udp(ip(0.0.0.0) port(514));
};
source s_net { tcp(ip(10.1.0.2) port(5441) tls(
ca_dir("/etc/syslog-ng/ca.d")
key_file("/etc/syslog-ng/newCA/serverkey.pem")
cert_file("/etc/syslog-ng/newCA/servercert.pem")
peer_verify(optional-untrusted)) ); };
destination d_cons { file("/dev/console"); };

If I try to start syslog-ng via systemctl, this is what happens:
# systemctl start syslog-ng
Job for syslog-ng.service failed because the control process exited with
error code. See "systemctl status syslog-ng.service" and "journalctl
-xe" for details.

It won't work.
If I change syslog-ng.conf to a specific IP in the source I get nearly
the same results.
One note: Occasionally, in the journalctl -xe, I get the following:
Oct 12 12:08:55 logger.com systemd[1]: Unit syslog-ng.service entered
failed state.
Oct 12 12:08:55 logger.com systemd[1]: syslog-ng.service failed.

But that doesn't show up all the time.
As far as options, it doesn't look like

Nothing seems to be blocking access to the log directory:
