Pulling forms from ODK Aggreagte using Briefcase

Welcome to the ODK forum, @KR! We're glad you're here. When you get a chance, please introduce yourself here. I'd also encourage you to add a real picture as your avatar because it helps build community!

If you get the forms lists on Briefcase after setting the Aggregate URL and credentials, you should be OK on that front.

The log file briefcase.log could give us more information about this problem. Could you attach here, please?

Also, maybe there's some issue server-side. You could see if there's any warning or error level messages in the logs at https://console.cloud.google.com/logs/viewer
