error deleting instance of group %s: %w

Error message

error deleting instance of group %s: %w

What it means

In RenderScw's scale-down loop, DeleteServer failed for one of the surplus instances selected for removal (taken from the head of the group's server list). The instance group name identifies the group; the wrapped error explains the deletion failure (locked server, API error).

Solutions

1. Check the wrapped error for the delete failure
2. Verify the server is not locked or in transition
3. Retry the apply; already-deleted servers are tolerated by DeleteServer's 404 handling
