Logstash kafka input not working

Elastic Stack Logstash
1

Hello,
I have this very simple logstash config:

input 
{ 
    kafka 
    { 
        topics => ["analytics"]
        bootstrap_servers => "HSTSCSRP2:9092"
		auto_offset_reset => "earliest"
    } 
}

output 
{
	elasticsearch 
    { 
        hosts => "HSTSCSRP1:9200"
        index => "events_2019_05_07"
    }
}

And I start it via bin\logstash -f config\logstash.conf

No matter what I do, I just can't see anything sent to ES. I tried to replace output to

output {
  stdout {}
}

And I don't see any output.
I can confirm the topic exists and new events are sent every second - if I open a Kafka consumer with the same topic and host, I see output:
c:\kafka\bin\windows\kafka-console-consumer.bat --zookeeper HSTSCSRP2 --bootstrap-server HSTSCSRP2:9092 --topic analytics
^ this works.

Logstash version is:

Sending Logstash's logs to C:/logstash/logs which is now configured via log4j2.properties
logstash 6.2.3
jruby 9.1.13.0 (2.3.3) 2017-09-06 8e1c115 Java HotSpot(TM) 64-Bit Server VM 25.211-b12 on 1.8.0_211-b12 +indy +jit [mswin32-x86_64]
java 1.8.0_211 (Oracle Corporation)
jvm Java HotSpot(TM) 64-Bit Server VM / 25.211-b12

There are no errors in logs.. HSTSCSRP2 is same server btw, I'm working on localhost.

Any help would be appreciated.
Thanks!

Adding some info (first post was limited in length) - this is logstash command output:

Sorry for bumping it got buried real quick..

Thanks.

Bump again - I noticed this part that says thread is in sleep. I have another machine with the exact same config and versions where it works, and there it says 'run'.

Maybe its related?
I really don't understand whats going on its like logstash don't work at all, but with the same config and installation on a different machine everything works. No error in logs.

Any help?
