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

Desired behavior:

Be able to run tests.

Versions

Cypress 3.7.0 Mac OS Mojave, 10.14.4 Node v8.16.2 Yarn v1.15.2

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.

@doitadrian I’ll try editing the hosts file tomorrow

Zach I am thinking right here at this error we can say “here is a link to debug this error”

On my end, the only thing I received was:

And of course, the ECONNREFUSED errors in the console, which wasn’t very helpful, hence this issue.
