EgoTracks dataset download not working even with proper credentials

[chorongi]

Hello. I have gotten credentials and I have successfully downloaded ego4d viz dataset, annotations with the following command.
ego4d --output_directory="~/scratch/data/tracking/ego4d" --datasets viz annotations
I can also check that the metacsv is properly loaded even for the full_scale dataset.
However, I am not able to download the egotracks dataset.
ego4d --output_directory="~/scratch/data/tracking/ego4d" --datasets egotracks

Which gives Error:
botocore.exceptions.ClientError: An error occurred (403) when calling the HeadObject operation: Forbidden

Would there be a reason why something would be possibly going wrong?
