Unable to download Sentinel-1 burst through asf_search

Hello,
I am encountering 401 errors when trying to download Sentinel-1 burst data using asf_search, but other data such as OPERA-S1 CSLC seems OK. Downloading through Vertex also works.

There are no system problems, so the issue may be if you are attempting to use token authentication, which is not supported for bursts.
Let us know if this is not the case, and perhaps an example of the authentication method you're using.
Thank you.

Thank you for the reply, I am using token authentication because it seems our proxy makes it impossible to login with auth_with_creds() on our R&D machines.
May I ask why the authentication methods do not work the same?

Token authentication wasn't included at the time burst distribution was implemented, but it is a feature we hope to add in the near future.
