Install filter-plugin failed

Today I upgraded logstash to the latest version and needs to install logstash-filter-elapsed plugin.
I'm receiving below error:

./logstash-plugin install logstash-filter-elapsed
Using bundled JDK: /usr/share/logstash/jdk
warning: no jvm.options file found
ERROR: Something went wrong when installing logstash-filter-elapsed, message: Socket closed

probably some ports I need to have open. Can someone tell me which ports I need to have opened to have ability to install plugins ?
