Rails/Nginx/Capistrano/Puma: (111: Connection refused) while connecting to upstream

ruby-on-rails-4 nginx connection capistrano3 puma

So the solution was to restart puma.

cap production deploy:restart

Every time I reboot the server, I need to restart puma as well.

ruby-on-rails-4 nginx connection capistrano3 puma

My recommendation is to check

~/apps/appname/shared/log/puma.stderr.log

log file. You may find there the answer

ruby-on-rails-4 nginx connection capistrano3 puma

looking at log/puma_error.log i saw the error (LoadError while trying to load bundler), doing gem update --system fixed it.
