Hi Neil,
According to your screenshot, this error can occur for 2 reasons:
1. If you don’t have storage admin access on your service account, or
2. If your storage Bucket doesn’t have public access.
So, can you please check for both of these issues from your Google Cloud Console, and try to connect Google Cloud again.
Also, you can create a new service account with storage admin access to troubleshoot thoroughly.
And if the problem still persists, please let us know, we will try to solve your problem.
Thank you.
Rafi
