No logs except internal syslog-ng logs are coming through Elasticsearch

What I did:

I ran loggen.sh to generate 100 random log entries
image

I've installed syslog-ng as a client on a Ubuntu 20.04 and configured it to connect with the remote syslog-ng server dockerfile. This is part of my syslog-nf configuration:
image

Full configuration:

@version: 3.25
@include "scl.conf"

# Syslog-ng configuration file, compatible with default Debian syslogd
# installation.

# First, set some global options.
options { chain_hostnames(off); flush_lines(0); use_dns(no); use_fqdn(no);
          dns_cache(no); owner("root"); group("adm"); perm(0640);
          stats_freq(0); bad_hostname("^gconfd$");
};

# Include all config files in /etc/syslog-ng/conf.d/

@include "/etc/syslog-ng/conf.d/*.conf"

Result expected:

The logs should be sent to the syslog-ng server inside the docker. I've also written the results to /var/log/message.
Here is a part of that file:
image
As you can see there are some entries for auth.log and some other stuff

Actual results:

None of the random logs generated or auth logs from my client are getting through Elasticsearch.
My Elasticsearch looks like this:
image
That's if I use extras/loggen.sh from the host that I've installed the dockerfiles on and also the log files that are sent from the Ubuntu client.
As you can see the Ubuntu client still connects to the syslog-ng server.

Am I doing something wrong?

Must have been the timezone issue, I am checking, I will let you know !, Also can you test the dev branch and see if you still see same issue ?
