Permission denied in omkafka module of rsyslog

I am trying to publish messages from rsyslog to kafka on a remote machine using omkafka module.

My omkafka action is configured as:
if $HOSTNAME == 'localhost' then {
    action(type="omkafka"
    name="log_kafka"
    broker="192.168.100.50:9092"
    topic="rsyslog_kafka"
    errorfile="/var/log/omkafka/log_kafka_failures.log"
    template="hostipFormat"<br/>
    )
}

My kafka instance is running fine and I am able to publish data using kafka-producer.bat file from another windows machine.

But when I start my rsyslog service, I get following error:

Feb 17 16:42:01 localhost rsyslogd: [origin software="rsyslogd" swVersion="8.24.0" x-pid="1764" x-info="http://www.rsyslog.com"] start Feb 17 16:42:05 localhost rsyslogd: omkafka: kafka message 192.168.100.50:9092/bootstrap: Failed to connect to broker at 192.168.100.50:9092: Permission denied [v8.24.0 try http://www.rsyslog.com/e/2422 ] Feb 17 16:42:05 localhost rsyslogd: omkafka: kafka message 1/1 brokers are down [v8.24.0 try http://www.rsyslog.com/e/2422 ] Feb 17 16:42:05 localhost rsyslogd: omkafka: kafka message 192.168.100.50:9092/bootstrap: Failed to connect to broker at 192.168.100.50:9092: Permission denied [v8.24.0 try http://www.rsyslog.com/e/2422 ] Feb 17 16:42:05 localhost rsyslogd: omkafka: kafka message 1/1 brokers are down [v8.24.0 try http://www.rsyslog.com/e/2422 ]

I am not sure whether this is related to omkafka or librdkafka.

Need help.

Solution

I got the reason of this issue. It happened because of SELINUX in centos. Once I disabled the SELINUX service, the configuration is working fine.
