Hello,
Please perform client development on Puzzle 38 (the test pool). Under normal conditions, you can request up to 120 ranges per minute. However, if you request too many ranges outside the test pool and do not return them, you may be temporarily banned from the system.
The error you are receiving is not related to rate limiting — it indicates that your account has been temporarily banned. This ban lasts for 24 hours.
My recommendation is to create a new test account and perform your testing on Puzzle 38. This way, you will not encounter these errors.
Thanks.
