PhantomJS, Capybara, Poltergeist failed to reach server - ruby-on-rails

Question

I'm working with poltergeist for the first time, so I don't really know what I'm doing but I couldn't find any solution on the web. Please tell me if any information is missing.
Error message:
Capybara::Poltergeist::StatusFailError: Request failed to reach
server, check DNS and/or server status
this issue doesn't happen on production but only on development and staging environment.
This line of code is the one that is making the trouble
phantomjs_options: ['--ignore-ssl-errors=yes', '--ssl-protocol=any', '--load-images=no', '--proxy=localhost:9050', '--proxy-type=socks5']
without '--proxy=localhost:9050' everything's working perfectly on every environment but I don't want to delete it in case it's critical for the production.
I've also noticed that on staging/development there's no 9050 port listening but on production there is one
full config code part (capybara_drivers.rb):
Capybara.register_driver :polt do |app|
Capybara::Poltergeist::Driver.new(
app,
js_errors: false, # break on js error
timeout: 180, # maximum time in second for the server to produce a response
debug: false, # more verbose log
window_size: [1280, 800], # not responsive, used to simulate scroll when needed
inspector: false, # use debug breakpoint and chrome inspector,
phantomjs_options: ['--ignore-ssl-errors=yes', '--ssl-protocol=any', '--load-images=no', '--proxy=localhost:9050', '--proxy-type=socks5']
)
end

Answer 1

Sounds like your production environment needs to make outbound connections through a socks5 proxy, and your other environments don't. You'll need to make the configuration dependent on environment
Capybara.register_driver :polt do |app|
phantomjs_options = ['--ignore-ssl-errors=yes', '--ssl-protocol=any', '--load-images=no']
phantomjs_options.push('--proxy=localhost:9050', '--proxy-type=socks5') if Rails.env.production?
Capybara::Poltergeist::Driver.new(
app,
js_errors: false, # break on js error
timeout: 180, # maximum time in second for the server to produce a response
debug: false, # more verbose log
window_size: [1280, 800], # not responsive, used to simulate scroll when needed
inspector: false, # use debug breakpoint and chrome inspector,
phantomjs_options: phantomjs_options
)
end
