stix bundle download was unsuccessful

Hi team,

So I am trying to sync my ATT&CK workbench with the ATT&CK website. It is currently hosting on a virtual machine in Azure.

When I tried to do this setup way earlier, I did not have any issue, but now when I try to run the python3 update-attack.py, I get this error "http://localhost/api/stix-bundles/?domain=enterprise-attack stix bundle download was unsuccessful"

I tried to troubleshoot the issue as to what has changed from the last time I tried this on my local virtual machine. I can make the following observations:

1. The version of workbench used is newer compared to the one I had worked with before.
2. There is a login capability for Workbench.
3. When I try to view the stix bundle page, I get the message Not Authorized. This message is only fixed when I login into the Workbench and then try again to view the page.

Is this a known Bug/error, please let me know. Also, the version of ATT&CK I was trying to use was the latest one (v12.1)

Start with update-attack.py and reproduce the STIX bundle download against the reported /api/stix-bundles/?domain=enterprise-attack endpoint. Check how the script handles the Workbench login and the endpoint's Not Authorized response; done means the v12.1 bundle downloads successfully in the reported setup.
