Hi stephenblender,
I have an answer from our admin, and he confirmed that you have been banned, manually in fact. It happens when when someone massively exceeds requests limit specified in our docs, precisely 10reqs pr/min. Please make sure to read these docs:
https://www.highcharts.com/docs/export- ... mer-export
Of course we will release this and you will be able to make requests again, but first we need to ask you to correct your code according to our terms of use. Let me know once that is done and our admin will release the ban.
Regards!
