Hello, error 429 means that we specifically had to block your account or project to resolve an outage affecting all users of KoboToolbox. The problem should not be related to the number of submissions, which in your case is fairly low, but rather the quantity of requests to our servers. Are you running some kind of automated task to download the data or otherwise interact with the API?
The block has been lifted but will be added again if needed to prevent the servers from being overwhelmed.
