Peer certificate cannot be authenticated

I installed this:

cargo 1.29.0-nightly (6a7672ef5 2018-08-14)

And I'm trying to build https://github.com/nokia/nperf but it can't download dependencies:

 Downloading log v0.4.4
error: unable to get packages from source                                                                                                                                                                   

Caused by:
  [60] Peer certificate cannot be authenticated with given CA certificates (SSL certificate problem: unable to get local issuer certificate)

It is probably something to do with the corporate network security but cargo doesn't even tell me what URL it is trying to download so how do I diagnose it? "cargo fetch -vv" displays the same output as "cargo fetch", which seems strange. "cargo update" works fine.

I figured out how to add the necessary root CA, but still, why didn't it display the URL that failed?

Thanks for the report! Good to hear it's working now, and I'm hoping that #5926 will make this a bit easier to diagnose in the future
