ssl_connect返回= 1 errno = 0 state = sslv2 / v3读取服务器hello未知协议rails 4

Question

我试图解决它，但无济于事。请帮忙。

config.action_mailer.raise_delivery_errors = true
  # config.assets.debug = true
  # config.action_mailer.perform_deliveries = true
    config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
  address:              'smtp.gmail.com',
  port:                 '587',
  domain:               'gmail.com',
  tsl: true,
  user_name:            'email@gmail.com',
  password:             'password',
  authentication:       :plain,
  ssl: true,
  enable_starttls_auto: true ,
  openssl_verify_mode: 'none'
  }

错误：SSL_connect返回= 1 errno = 0状态= SSLv2 / v3读取服务器问候A：未知协议

当我在网上搜索时，他们只需添加一行＆＃34; enable_starttls_auto：true，openssl_verify_mode：＆＃39; none＆＃39; ＆＃34;将以错误结束，但它仍然无法解决我的问题。

请试试这个：

 ActionMailer::Base.smtp_settings = {
  :address        => 'smtp.sendgrid.net',
  :port           => '587',
  :authentication => :plain,
  :user_name      => ENV['SENDGRID_USERNAME'],
  :password       => ENV['SENDGRID_PASSWORD'],
  :domain         => 'heroku.com',
  :enable_starttls_auto => true

 }
