Ruby on rails sslv3 alert handshake failure - ruby-on-rails

Question

I am trying to make HTTPS API request to Salesforce instance. I am trying to connect from localhost and windows machine.
SALESFORCE_URL = "https://my.salesforce.com"
TOKEN_URL = "services/oauth2/token"
request_params = {
"grant_type" => "password",
"client_id" => "3MVG9gOZsF7exF8Pn79zdsxuntzX_0TlVPRKL0R8iPxBQ8dHqh14yzg",
"client_secret" => "272142298328091392325",
"redirect_url" => "https://localhost:3000/RestTest/oauth/_callback",
"username" => "user#xyz.com",
"password" => "xyz#2018",
}
url = SALESFORCE_URL + "/" + TOKEN_URL
uri = URI.parse(url)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
request = Net::HTTP::Post.new(uri.path, initheader = {'Content-Type' =>'application/json'})
request.body = request_params.to_json
response = http.request(request)
Rails.logger.info response.inspect
I am getting below error.
OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: sslv3 alert handshake failure

Why I am getting this error?

Answer 1

Salesforce does not support SSLv3 (POODLE Vulnerability).
Check the suported ciphers using online tools like Comodo's SSL Analyzer or Qualys SSL Labs and configure your HTTP client
connection.ssl_version = :TLSv1 or :TLSv1_2
