How to get rid of OpenSSL::SSL::SSLError

I am trying to authenticate users with Facebook using OmniAuth. Initially, it was working, but along the way it just stopped working and started to give me this error message:

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

The same code works well for Twitter and I can't seem to understand why it doesn't work for Facebook. I have looked online for help, but I haven't been successful.

This is the link to the website I am building: And this url would give you the error message:


Ruby cannot find any root certificates. Here is an option for debugging purposes. Put following code at the begining of your script:

   require 'openssl'

Add the following code to config/initializers/fix_ssl.rb

require 'open-uri'
require 'net/https'

module Net
  class HTTP
    alias_method :original_use_ssl=, :use_ssl=

    def use_ssl=(flag)
      self.ca_file = "/etc/pki/tls/certs/ca-bundle.crt"  # for Centos/Redhat
      self.verify_mode = OpenSSL::SSL::VERIFY_PEER
      self.original_use_ssl = flag


Many operating systems already come with a supplied certificate bundle. For example in Red Hat Enterprise Linux and CentOS it's installed in:


For Ubuntu its at:


I've been facing the same problem after updating Ruby running on Yosemite, but while trying to authenticate with Google.

Following this: seemed to solve my problem.

For the sake of history I'll quote:

So the rvm-installed ruby does look into the wrong directory for certificates whereas the OSX-ruby will look into the correct one. In it's case that is a OSX system-directory.

So the rvm-installed ruby is the problem.

This discussion on Github finally gave the solution: Somehow RVM comes with a precompiled version of ruby that is statically linked against an openssl that looks into /etc/openssl for it's certificates.

What you wanna do is NOT TO USE any of the precompiled rubies and rather have ruby compiled on your local machine, like so: rvm install 2.2.0 --disable-binary

In the end, I had to run:

rvm uninstall ruby-2.2.4
rvm install ruby-2.2.4 --disable-binary
gem pristine --all

Hope this helps

Looks like SSL verification is failing for Facebook. I'm no OpenSSL master, but I think this should work for you.

Assuming you're using an up-to-date version of OmniAuth (>= 0.2.2, I assume you are) and a version of Faraday >= 0.6.1 (the stack trace says you are), you can pass the location of your CA certificates bundle. Modify your OmniAuth setup for Facebook accordingly:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, 'appid', 'appsecret', {:scope => 'publish_stream,email', :client_options => {:ssl => {:ca_path => '/etc/ssl/certs'}}}
  # other providers...

and replace '/etc/ssl/certs' with the path to your bundle. If you need one, I believe this file will work for you--just put it somewhere, give it necessary permissions, and point your app at it.

Thanks to Alex Kremer at this SO answer for the detailed instructions.

This link should work. Just follow the instructions. You will need to download Rails installer and run two command line functions.

An ugly workaround I just did is to override the class in Net::HTTP and set the variable which tells it to not verify ssl certs:

    require 'net/http'
    require 'openssl'

    class Net::HTTP   alias_method :origConnect, :connect
        def connect
          @ssl_context.verify_mode = OpenSSL::SSL::VERIFY_NONE

I did it this way because I don't want to muck with the source code of the gem which calls the gem which calls the gem which calls Net::HTTP. I should really go back and figure out how to nudge it to look at a separate cacert.pem file instead. I can't modify the server's cacert.pem file, or that would be the best route.

Do this, this will get ride of the certificate error with openssl

sudo curl -o /opt/local/etc/openssl/cert.pem
