Looks like this form submitted by js, but the mechanize is not working with js actually
onclick="document.getElementById('pro_form1').submit();"
perhaps the changed of driver will help (selenium or poltergeist) with the creation of Capybara browser session.
or, as an option, just try to ignore SSL errors:
$m.verify_mode = OpenSSL::SSL::VERIFY_NONE
or i think, match better to use here the net-post request without mechanize, for me it's work fine:
url = URI("https://vpnstaticip.com/create-account.php?trial=1")
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Post.new(url)
request["content-type"] = 'application/x-www-form-urlencoded'
request.body = "name=name&email=me%2540mail.com&country=217&username=Username&terms=1&nospam=nospam&submitted=1"
response = http.request(request)
puts response.read_body
=> ERROR: Username already exists. Try different one
besides, i can't reproduce the "Email is too long" error, so please, let me know if the problem is still persist, thanks
