I train training a new version of this model. However, I keep receiving this error shown in the screenshot below. Any help will be appreciated.

I have the same error. I tried to change the API key, and creating a new version, but the error persists.  
Also, when I try to download a previous version of this dataset (which I trained before a model without any problem), it can not be downloaded.

I managed to train my dataset after downloading it as a ZIP file but I still do not know what is the problem here. If the error is still not fixed, just download it as ZIP file. Extract ZIP file and upload it to your google drive and use google colab to train your dataset. I cna help you some code snippets if you are still facing any issues.
