Trouble Downloading DSCOVR EPIC MAIAC Data (01/06/2021 - 30/11/2021)

I'm trying to download data from the DSCOVR EPIC MAIAC dataset, but I keep running into issues. I've tried the following methods without success:

- Data Download App
- Cygwin Terminal
- Manual Download: https://asdc.larc.nasa.gov/data/DSCOVR/EPIC/L2_MAIAC_02/2021/06/


I'm specifically trying to get data from June 1, 2021, to November 30, 2021. No matter what I do, I can't seem to download the files.

I've attached screenshots of the errors I encountered with each method to help diagnose the problem.

ASDC data pages for individual months of data, such as
https://asdc.larc.nasa.gov/data/DSCOVR/EPIC/L2_MAIAC_02/2021/06/
https://asdc.larc.nasa.gov/data/DSCOVR/EPIC/L2_MAIAC_02/2021/07/
etc. currently work OK

instructions on how to download data with wget and python scrips are available at viewforum.php?f=7&sid=6967a8430c1959276aac21d89b560ed5&DAAC=1&Discipline=&Projects=&ServicesUsage=15,16&keywords=&author=&startDate=&endDate=&bestAnswer=&tagMatch=all&searchWithin=all.

Another way to get the data is through the Earthdata search page, https://search.earthdata.nasa.gov/. Once you are on that page, search for DSCOVR_EPIC_L2_MAIAC_02. You will see
