Do I do this on my Windows server or the test restore VM?

I've tried looking at the bootable ISO image to see if I could submit a support ticket from there but there's only a feedback button. As for the Windows Server, there won't be anything in the logs to help the support team find the error.

Thanks

Version 6.3.2.212

Yes, that's correct.

I've copied/pasted the Account ID & Application Key so I know the details are correct.

I just tried resetting my B2 Application key and then copied and pasted it into my test restore VM. Because I copied/pasted it, I know that it has been correctly entered in.

Despite this, once I try to select the bucket, I get an error saying "bad_auth_token". See attached

When I made the ISO image from my windows installation, doesn't it define the B2 storage itself?

Add on:
When I made the ISO image in the previous versions, it would simply work and define all of the storage accounts itself. When I made this ISO using the new version, it made all of the storage accounts again by itself but this time they don't connect.
