Misleading error instead of denied: registry contains 1 repositories, limit is 1

Is this an upstream issue?

```
error: failed to solve: failed to fetch oauth token: unexpected status: 403 Forbidden
```

vs what you get in docker push manually

```
denied: registry contains 1 repositories, limit is 1
```
