Recently, I have seen a few remote (aws-over-vagrant) system tests fail during setup due to this error:
```

```
The problem is transient, so it seems to be an issue with the SSL negotiation on the server side. Some reading has suggested it could also be due to networking issues when running inside of containers, or over VPNs, etc., etc.
I didn't find anything obvious we could do about it, so it seems worthwhile to at least attempt to avoid failing the whole run over a transient non-problem.
