cypress: cypress reloads in infinite loop when calling cy.visit to http URL that upgrades to https.

Current behavior

When visiting a page that triggers certain redirects, the test runner keeps reloading and looping endlessly.

Desired behavior

Not reload the test runner and follow redirects.

Test code to reproduce

describe('example cypress reload issue', () => {
  it('keeps reloading', () => {
    cy.visit('https://enexis.nl/mijn-enexis/mijn-aanvragen')
  })
})

We observed this unexpected looping behaviour when Cypress was running on https:// in the Chrome browser that it was driving. The server for our system under test (SPA web app) only supports the http:// protocol. When we manually removed the s in the URL bar in the Cypress-driven Chrome, it began behaving as expected again (no looping).

Between our tests running fine on Firefox and the comment above by @BevanR (thank you!), I’m wondering if this may be related to Chrome’s recent change to use HTTPS by default.

We’re narrowing in on a solution. So will hopefully have some updates soon on this.

UPDATED

Below instructions works around the issue, until a proper solution is made

Both PART1 and PART2 are required

PART1 - in it block

if(top.location.protocol == 'https:') {
    top.history.replaceState('', '', top.location.href.replace('https://', 'http://'))
}
cy.visit('http://httpforever.com')

PART2 - in cypress config

Hi, I’d like to get some understanding on why this workaround doesn’t work for people. To visit the correct URL to begin with. Is there a reason you need to visit the http or https and have it resolve to the other protocol?

We would recommend having your cy.visit visit the correct protocol (http/https) to avoid the redirection loop for now to get around this issue.

Internal (not exposed to the Internet) company apps generally use http

I am using the correct protocol (http) for the URL I’m visit’ing

@tudorgabriel the fix on Cypress’s side isn’t released yet

I updated the workaround here: https://github.com/cypress-io/cypress/issues/25891#issuecomment-1861098656

I am only seeing this with cypress open, I don’t see this with cypress run

Does anyone see the same?
