Hey, I am trying to build a Rust project on macOS. It seems like the part of “Installing Rust” fails with an SSL peer handshake failure for curl. I am pretty sure I didn’t change any configuration. This problem began showing up today.

A link for the failed job: [https://travis-ci.com/freedomlayer/offst/jobs/195238736](https://travis-ci.com/freedomlayer/offst/jobs/195238736)

Relevant error lines:

```bash

Upgrading to xcode9.4.1 solved the issue. Thanks!
