Twitter::Error::Unauthorized: Not authorized. using user_timeline


I’m looping through punch of users and getting their user_timeline. The code was working fine till two days ago but just started getting Twitter::Error::Unauthorized: Not authorized error all of the sudden.

Here is the code

client = initialize_twitter
@tweets = client.user_timeline(username,{:count =>  200})

  def self.initialize_twitter do |config|
      config.consumer_key        = "xxxx"
      config.consumer_secret     = "xxxx"
      config.access_token        = "xxxx"
      config.access_token_secret = "xxxx"
