Ok ,I have read and do that , but it doestn't work for me .  
I used this for download plugin : [search | RubyGems.org | your community gem host](https://rubygems.org/search?query=logstash-filter-sns)

I tried , I administer the FW and I don't have any filter for my server .  
It's work with another connexion so .. the problem is the FW but I don't see anything 🙂

A question, when I launch Logstash, it tells me that it cannot find the configuration file which is in /etc/logstash/logstash.yml.  
I had to force it with the -f option..  
How can I fix this?

Since the Ruby code is interpreted by JRuby, a Ruby interpreter written in Java, you can use various Java run-time options to do some serious debugging. Try starting the logstash-plugin utility like this:

```auto
$ export DEBUG=1
$ export LS_JAVA_OPTS="-Djavax.net.debug=all"
$ bin/logstash-plugin install --no-verify logstash-filter-SNS

```

Maybe take a look if you have other, similar Java options defined in /etc/default/logstash, /etc/logstash/startup.options, /etc/systemd/...../logstash-something and add them to the LS\_JAVA\_OPTS variable.

For more information on the javax.net.debug option, look here: [Using java -Djavax.net.debug=… to examine data flows, including TLS – ColinPaice](https://colinpaice.blog/2020/04/05/using-java-djavax-net-debug-to-examine-data-flows-including-tls/)

I think that the problem come from my firewall .  
I didn't have any block message but I think that the NAT is not supported .

Thanks for your help !
