Empty response

[sabine....@gmail.com]

Sometimes I am getting an empty response after doing a valid authentication/signin on twitter when calling a Twitter rest api method

like get " http://api.twitter.com/1.1/friends/list.json.

I have tried the https url as well.  Sometimes that works, sometimes http works.

I get the access token back ok and the call doesn't fail, it is just empty?

@access_token = OAuth::AccessToken.from_hash(UsersController.consumer, @@token_hash )

# get the friends for this user

@response = @access_token.request(:get, @@twitter_friends_list_url)
