Verification of baseUrl is failing when using `hosts` in cypress.json

See original GitHub issue

Current behavior

Having a cypress.json like following

{
  "baseUrl": "http://wordpress.local",
  "hosts": {
    "wordpress.local": "121.0.0.1"
  }
}

When running cypress we get an unexpected behavior, Cypress fails to verify the URL.

We are verifying this server because it has been configured as your baseUrl.

Cypress automatically waits until your server is accessible before running tests.

Cypress failed to verify that your server is running.

However if we remove baseUrl from the cypress.json and we use cy.visit('http://wordpress.local/'); instead of cy.visit('/'); it work perfect.

{
  "hosts": {
    "wordpress.local": "121.0.0.1"
  }

Desired behavior

We are using a Linux base container like cypress/included:9.4.1 in our CI system so the error happens. However, it doesn’t happen locally using MacOS. You can see the following logs

───────────────────

The desired behavior is this working on a Linux system. The problem seems to be related to the verification of the baseUrl that is performed when it is found in the cypress.jso.

Test code to reproduce

Cypress.json

{
  "baseUrl": "https://google.local"
  "hosts": {
    "google.local": "216.58.214.142"
  }
}

spec.js

/// <reference types="cypress" />

it('Google is shown', () => {
    cy.visit('/');
    cy.get('img.lnXdpd').should('have.attr', 'src').should('include','googlelogo_color_272x92dp.png');
});

Cypress Version

9.4.1

Other

$ cypress --version
Cypress package version: 9.4.1
Cypress binary version: 9.4.1
Electron version: 15.3.4
Bundled Node version: 16.5.0

Hi! We have encountered the same problem but in our case, we cannot use the workaround proposed by @dani8art.

We need hosts and baseUrl configs working at the same time because we need to map the domain to an IP and, additionally, we need to avoid the “reloading error” in the middle of a test whose solution is to define the baseUrl ( tickets: https://github.com/cypress-io/cypress/issues/2636, https://github.com/cypress-io/cypress/issues/3454, https://github.com/cypress-io/cypress/issues/2777 … ).

So this is also critical for us and we can not use the workaround.

Wow, @funktionalsystems this is really great research, Since I saw that it was working depending on the OS I thought it might be related to “be some kind of runtime scope/timing issue”.

However, I can see this line

cypress:server:server-base Server listening on  { address: '127.0.0.1', family: 'IPv4', port: 46389 }

Which is always pointing to 127.0.0.1 instead of being pointing to $MY_REDACTED_IP as you have mentioned it may be related to “Perhaps this is somehow a bug in isListening (ensure-url.ts)”
