API does not respond in chrome launched by cypress locally

[mindaugasnakrosis]

Current behavior:

Test fails in Chrome browser launched by cypress.
API responds with an error: "err empty response".

If I reproduce the same test manually (chrome opened by me), API responds just fine (screenshots included).

If I launch backend code on 127.0.0.1:9090 rather than on localhost:9090 everything seems to work.

Desired behavior:

API responds correctly.

Are you behind a corporate proxy? Have you followed the instructions for Proxy Configuration? https://on.cypress.io/proxy-configuration

What version of Cypress are you using?

[mindaugasnakrosis]

I am not behind a proxy.
I am using 4.0.2 version.

Hey, I also have some trouble with local API testing. When I try to execute tests. All my XHR requests canceled & aborted.

I don't understand why it aborted in cypress's browser?
