Cypress browser give ERR_EMPTY_RESPONSE when open

[tiagocrizanto]

I cloned this repo https://github.com/thiagones/cypress_cocumber_poc in a PC without a coorporate proxy and it works, but if I execute this project behind a coorporate proxy I get ERR_EMPTY_RESPONSE error when browser is opened.
If I type any address I get this error. This is a simple project that open google site and search a term.

The left image is the chrome opened by cypress and the right image is chrome opened by user.

I followed this steps but it dont work https://docs.cypress.io/guides/references/proxy-configuration.html

I need to understand what cypress do when open a browser to try solve the proxy resolution with infrastructure. It creates a local proxy? Call external url's that could be blocked by firewall?
