We are using the ruby twitter gem (https://github.com/sferik/twitter) to connect to twitter, but I don’t think it is important here.
We have a cron job that fetches the latest entries of user timelines twice a day.
We are using Application-only authentication.
The first 50 or 51 out of 58 requests work fine and return the tweets
but all other fail with “Twitter::Error::Forbidden: Unable to verify your credentials”.
(Same happens if we use the reverse order of users)
According to https://dev.twitter.com/docs/rate-limiting/1.1/limits the rate limit is 300 requests per window
and shouldn’t be our problem.
Does anyone know what the issue might be?
