cypress: 3.7.0 - Cypress failed to make a connection to the Chrome DevTools Protocol

Current behavior:

Basically, I’m having the same issue mentioned in the #5431. I installed cypress via yarn add --dev cypress, and just wanted to run tests that were initially provided.

Logs (an excerpt) received after running DEBUG=* cypress open

Sorry if I missed some of the details, please let me know if I did.

Thanks for making this awesome piece of software 😃

P.S. When I run cypress run, which should I guess run tests via Electron, I can also see the ECONNREFUSED issues.
