OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed - rake task to external API

Question

I am trying to build a rake task that accesses the API of viglink, a url affiliating service.

However, when my rake task runs open(url), where url is an https uri, the error I get is:

rake aborted!
OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

I tried to fix this using this answer, but I get the same error

OpenSSL::SSL::SSLError on Heroku

Is anyone having a similar issue that isn't solved with the above ? I'm running this on a Digital Ocean droplet on Ubuntu 12.04.4 LTS (GNU/Linux 3.8.0-29-generic x86_64)

relevant part of my rake task:

  url = "https://www.viglink.com/service/v1/cuidRevenue?lastDate=2014%2F12%2F23&period=week&secret=0d0dfillerb57acb4"
  response = open(url)

The error happens on the 2nd line.

Happy holidays!

Ran into the same problem when everyone started removing SSLv3 support. Your target site has done the same:

nmap --script ssl-enum-ciphers -p 443 www.viglink.com

Starting Nmap 6.40 ( http://nmap.org ) at 2014-12-25 08:16 EST

Solution is to update openssl on your machine.

openssl version
OpenSSL 1.0.1f 6 Jan 2014

My response without error:

require 'open-uri'
url = 'https://www.viglink.com/'
response = open(url)
# => #<Tempfile:/tmp/open-uri20141225-19253-qhcgcg>
puts response.base_uri
# => https://www.viglink.com/
