nylas-mail: Error after authenticating - `We were unable to reach your mail provider. Please try again.`

What operating system are you using?

macOS 10.12

What version of N1 are you using?

Nylas Mail 1.0.8

Is the issue related to a specific email provider (Gmail, Exchange, etc.)?

Gmail

When I try adding my Gmail account to Nylas, allowing Nylas to use services, and after seeing the “You’re all set!” message, my Nylas window doesn’t do anything. Opening up the developer toolbar yielded this message:

Then I can’t go any further. This happens every time I try to add my Gmail account.
