Hi, I'm trying to use ssl for tcp output plugin for logstash. The workflow goes to a nginx-proxy ssl termination point for logstash that will forward the logs to a logstash pod that takes in tcp input. My output part for logstash looks like this: output { tcp { host =\> "172.20.45.41" port =\> 30002 ssl\_enable =\> true ssl\_verify =\> false ssl\_cacert =\> "/usr/share/logstash/ca/ca.crt.pem" ssl\_cert =\> "/usr/share/ssl/client.crt" ssl\_key =\> "/usr/share/ssl/client.key" codec =\> json\_lines } } The client.crt and key have been created from the client cert/private key pair in the nginx-proxy server. Has anyone seen an error like this? SSL Error {:exception=\>#\, :backtrace=\>["org/jruby/ext/openssl/SSLSocket.java:266:in `connect'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-output-tcp-5.0.3/lib/logstash/outputs/tcp.rb:179:in`block in connect'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/stud-0.0.23/lib/stud/try.rb:79:in `block in try'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/stud-0.0.23/lib/stud/try.rb:95:in`block in try'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/stud-0.0.23/lib/stud/try.rb:20:in `each'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/stud-0.0.23/lib/stud/try.rb:91:in`try'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/stud-0.0.23/lib/stud/try.rb:123:in `try'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-output-tcp-5.0.3/lib/logstash/outputs/tcp.rb:174:in`connect'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-output-tcp-5.0.3/lib/logstash/outputs/tcp.rb:151:in `block in register'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-codec-json_lines-3.0.6/lib/logstash/codecs/json_lines.rb:48:in`encode'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-output-tcp-5.0.3/lib/logstash/outputs/tcp.rb:201:in `receive'", "/usr/share/logstash/logstash-core/lib/logstash/outputs/base.rb:89:in`block in multi\_receive'", "org/jruby/RubyArray.java:1734:in `each'", "/usr/share/logstash/logstash-core/lib/logstash/outputs/base.rb:89:in`multi\_receive'", "org/logstash/config/ir/compiler/OutputStrategyExt.java:114:in `multi_receive'", "org/logstash/config/ir/compiler/AbstractOutputDelegatorExt.java:97:in`multi\_receive'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:373:in `block in output_batch'", "org/jruby/RubyHash.java:1343:in`each'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:372:in `output_batch'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:324:in`worker\_loop'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:286:in `block in start\_workers'"]} ---

Found the cause last week; it was because of the certificate I was using was being revoked by CRL in nginx proxy. ---
