Why does my backup to bucket storage fail when Test connection works?
Short answer: Older versions could pass Test connection while a backup to non-Amazon bucket storage failed — that bug is fixed, so update and retry. If it persists, check the Bucket and Endpoint URL are set and exactly right.
In older versions, Test connection checked the account while the backup could still fail with a message about connecting to storage on non-Amazon services — that was a bug, and it's fixed. Update Storage Studio and run the backup again; there are no settings to change.
If it still fails on the latest version, check that the Bucket is set and correct (a missing bucket passes a simple test but breaks every transfer), and that the endpoint matches your provider's dashboard exactly.
