Added new provider for NASA PODAAC products : Not able to download them

[annesophie-cls]

Hi,

I added a new provider for the STAC NASA PODAAC catalog : https://cmr.earthdata.nasa.gov/cloudstac/POCLOUD/ But i don't succeed to download products, as I get a 401 Unhautorized Error. However, from my web browser I don't have any problem to download the product from the downloadLink.

Please have a look at the notebook screenshot, that is trying to download this product : https://cmr.earthdata.nasa.gov/cloudstac/POCLOUD/search?ids=ascat_20230620_092700_metopb_55801_eps_o_250_3301_ovw.l2 But only the .png data is downloaded, not the .nc data.

And this is the provider configuration :

Did I write something wrong in the provider configuration ?

Thank you very much
