I am using the GET statuses/retweets/:id to get the 100 retweets for tweets identified by their ids. Until a few days back I was able to get this data without any problems maintaining the 350 request/hour threshold. For the past few days I am finding that the program I use for collecting the retweets is behaving strangely. For the first few ids I am getting the retweets and after that for all subsequent requests I am getting the following error: “Basic authentication is not supported”. Could someone please tell me what is going on? FYI, I am using the Perl library Net::Twitter for this.
