Capistrano cap production deploy:initial Net::SSH::ConnectionTimeout - ruby-on-rails

Question

I am following this tutorial for setting up a webserver for a simple rails app: https://www.digitalocean.com/community/tutorials/deploying-a-rails-app-on-ubuntu-14-04-with-capistrano-nginx-and-puma with nginx and capistrano.
my deploy.rb file:
# Change these
server '45.33.11.11', port: 22, roles: [:web, :app, :db], primary: true
set :repo_url, 'git#bitbucket.org:slucha/supplement.git'
set :application, 'supplementtests'
set :user, 'deploy'
set :puma_threads, [4, 16]
set :puma_workers, 0
# Don't change these unless you know what you're doing
set :pty, true
set :use_sudo, false
set :stage, :production
set :deploy_via, :remote_cache
set :deploy_to, "/home/#{fetch(:user)}/apps/#{fetch(:application)}"
set :puma_bind, "unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock"
set :puma_state, "#{shared_path}/tmp/pids/puma.state"
set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
set :puma_access_log, "#{release_path}/log/puma.error.log"
set :puma_error_log, "#{release_path}/log/puma.access.log"
set :ssh_options, { forward_agent: true, user: fetch(:user), keys: %w(~/.ssh/id_rsa.pub) }
set :puma_preload_app, true
set :puma_worker_timeout, nil
set :puma_init_active_record, true # Change to false when not using ActiveRecord
## Defaults:
# set :scm, :git
# set :branch, :master
# set :format, :pretty
# set :log_level, :debug
# set :keep_releases, 5
## Linked Files & Directories (Default None):
# set :linked_files, %w{config/database.yml}
# set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
namespace :puma do
desc 'Create Directories for Puma Pids and Socket'
task :make_dirs do
on roles(:app) do
execute "mkdir #{shared_path}/tmp/sockets -p"
execute "mkdir #{shared_path}/tmp/pids -p"
end
end
before :start, :make_dirs
end
namespace :deploy do
desc "Make sure local git is in sync with remote."
task :check_revision do
on roles(:app) do
unless `git rev-parse HEAD` == `git rev-parse origin/master`
puts "WARNING: HEAD is not the same as origin/master"
puts "Run `git push` to sync changes."
exit
end
end
end
desc 'Initial Deploy'
task :initial do
on roles(:app) do
before 'deploy:restart', 'puma:start'
invoke 'deploy'
end
end
desc 'Restart application'
task :restart do
on roles(:app), in: :sequence, wait: 5 do
invoke 'puma:restart'
end
end
before :starting, :check_revision
after :finishing, :compile_assets
after :finishing, :cleanup
after :finishing, :restart
end
# ps aux | grep puma # Get puma pid
# kill -s SIGUSR2 pid # Restart puma
# kill -s SIGTERM pid # Stop puma

# Load DSL and Setup Up Stages
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rails'

Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

install_plugin Capistrano::SCM::Git
Nginx is installed, ssh keys are set up for both bitbucket ssh and deploy keys for the repo and rvm ist also installed on the server
The cap staging deploy:check command passes without errors but when I try to run cap production deploy:initial I get the following error
** Invoke production (first_time)

Any ideas why there is a timeout?
UPDATE
ssh -T git#bitbucket.org gives message:

ssh -T deploy#45.33.95.53 gives

Answer 1

The problem was that I had two conflicting settings between the deploy.rb and production.rb
make sure that your settings in both files are correct.
in my production.rb I had the following line:
server '53.33.95.53', user: 'deploy', roles: %w{web app}
Which was overwriting the current ip address and was causing the timeout.
