Hello! Can anyone tell me why the CI build failed? Thanks.

[Narretz]

Did you take a look at the logs on Travis? Usually they have some info. It's also possible that this is a flake.

@Narretz Yes I did. There is a connection refused:

20170615 000024.559 [4421] PROXY 127.0.0.1:35020 -> POST http://localhost:9876/socket.io/?EIO=3&transport=polling&t=Lof3Fvn&sid=r73fxRiwJquSKEYQAAAV (644 bytes)

20170615 000024.559 [4421] PROXY 127.0.0.1:35020 <- localhost:9876 connection error: Connection refused

Can you rebuild it?

Thanks!

[Narretz]

Restarted.

Note that this must be changed in https://github.com/angular/angular-phonecat, too. For that we also need to check we are using an up to date Protractor version.

Hello @Narretz. I can do it. Is there a problem updating Protractor version?

The tutorial changes (which are invalid as they are in this PR) are being taken care of in #16753 and angular/angular-phonecat#430.
The other e2e change is valid 👍
