I have been running into a recurring problem that I have been facing for the past couple of days, on numerous machines.
I am extracting 200 tweets for a large number of users, using the numeric user ID (user_id). After a small number of requests (between 10 and 50) I receive nothing but "This method requires authentication". Authenticating with my username and password does not make the message go away. I have verified that the users I am trying to pull are not protected users. I have also verified that I am not hitting the rate limit. On my latest attempt, I used an IP I have not used in the past. I was able to extract the first 200 tweets for *12* users, then I started receiving 401s ("This method requires authentication") on every single request of this type. After about 10 minutes, I tried again and it worked for about another 15 users, then I started getting the same message as well as other messages including 502. Is this behavior expected? Does this 401 message possibly mean something else?
