I am using logstash-6.1.1 on linux
While installing plug-in , I am getting following error,
$ ./logstash-plugin install logstash-output-gelf
Unable to download data from https://rubygems.org - timed out (https://api.rubygems.org/latest_specs.4.8.gz)
ERROR: Installation aborted, verification failed for logstash-output-gelf
$ ./logstash-plugin install --no-verify logstash-output-gelf
ERROR: Something went wrong when installing logstash-output-gelf, message: Failed to open TCP connection to artifacts.elastic.co:443 (execution expired)
