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.
