Error Retrieving Ancillary Filelist by getanc

[alakes]

Hi Everyone,
I routinely process MODIS Aqua and VIIRS-SNPP data from the Ocean Color Web from Level-1A to Level-2 as part of my daily operations, using SeaDAS 9.0.1 with processing tag V2025.5 for VIIRS-SNPP and using SeaDAS 7.5.3 for MODIS-Aqua.

Recently while running the getanc command I am getting the following error.

/home/o-mc/SeaDAS901/ocssw/bin/getanc V20251108T083600.L1A_LAC --no2 --verbose --refreshDB --force-download --timeout=90 -m viirsn

I also tried with the SeaDAS 7.5.3. installation which gives the same error.

/home/o-mc/SeaDAS7.5/ocssw/scripts/getanc.py V20251108T083600.L1A_LAC --no2 --verbose --refreshDB --force-download --timeout=90 -m viirsn

I am also getting the same error while running the command for MODIS-Aqua in both SeaDAS 9.0.1 and SeaDAS 7.5.3 - for example

/home/o-mc/SeaDAS7.5/ocssw/scripts/getanc.py A2025313143000.L1B_LAC --verbose --refreshDB --force-download --timeout=90 -m aqua

Can anyone help how to solve this issue and shed some light if the issue of my SeaDAS installation, or this error is server related?

I would like to mention that the commands were working fine until 3–4 days ago. My internet connection is stable, as I am able to download L1A_LAC files from the Ocean Color Web without any issues. Reinstalling the processing tag did not resolve the problem either.

Thanks in advance for your help.
