VIIRS Nighttime Lights Error: Received an HTML response, which likely indicates an invalid/expired NASA Earthdata Token

Hello,

I've been using Nighttime Lights data from VIIRS a lot at work over the past few months without an issue, but I suddenly ran into this error today when trying to download a monthly raster (VNP46A3). I double-checked my token and it was still active and worked perfectly just a month ago, I also made sure I had agreed to all of the EULAs and had all the necessary profile information. I even generated new tokens and was still unable to avoid this error. Is there anything I can do to fix this issue or check the validity of my tokens? Happy to provide any additional details.

Have you tried downloading files using wget command provided on "See wget Download Command" tab at the top of the archive page to test your token:

Apologies for the late reply. I've tried the wget method and it worked just fine, so I'm thinking the problem may be a recent issue with how the World Bank's blackmarble API interacts with the data retrieval process.
