Hi!
I use the ASF bulk download python script to download S1 files, but it fails.
I set the study area and accept all eulas in my profile. I checked the ".bulk_download_cookiejar.txt" file in my home dir (suggested in a previous post), but it doesn't exist.
I appreciate any help. Thanks.

Re: Problem with bulk download python script
Hello,
I have just used the bulk download script with no authentication issues. This is after I deleted an existing bulk_download_cookiejar.txt, so I had to log in again before the download would execute. So I know the bulk download service is working.
Please try this: While logged in to Vertex, see if you can download a file directly by clicking the down arrow next to the filename in the right column of the results window.
Thanks.
