protractor: Error: ECONNREFUSED connect ECONNREFUSED after Chrome version update

My protractor e2e tests have suddenly stopped working. I’m getting the error:

My tests worked this morning, and I haven’t made any changes to the config since then. The only thing I can think of is Chrome recently updated to v54. The same failure is happening on multiple machines.
