Application navigated using cy.origin is not able to open the page that appends dynamic key params to it

[varikaurtest]

I am automating a flow that involves 2 applications (both on different origins). I generated some data on application 1 and now want to validate the same in application 2, thus navigated to new using cy.origin

function login(username: string, password: string) {
cy.visit('/')
cy.origin('https://***//', {args: {username, password }}, ({username, password}) => {

cy.get('uname').type(username);
cy.get('#password').type(password);  
cy.get('loginBtn').click()  

}

In the same application2, I am able to perform various actions by calling the POM methods where the URL is static pages e.g. /payments or /search etc except at one click where the URL adds dynamic hostKey and other details to its URL. Observed that the URL is not changing on the click and the page remains in loading state forever.

Has anyone faced and solved this issue, please confirm.

Core problem
Static routes work correctly inside cy.origin(), but navigation fails when a click triggers a redirect that: causes a full page reload, and/or appends runtime-generated query parameters (e.g. hostKey, tokens).

Observed behavior
The click is executed successfully. Cypress does not detect the resulting navigation. The page remains stuck in a loading state.

Why this appears Cypress-related
This appears to be a limitation of cy.origin() when handling:
full page reloads triggered by user interactions,
navigations that modify the URL using runtime-generated parameters,
redirects that Cypress does not recognize as navigation events.

SPA vs full page reload

Static SPA routes (e.g. /payments) work because they rely on client-side routing, which Cypress can track reliably.
Dynamic redirects often trigger full page reloads, which cy.origin() may not consistently reattach to or observe.

Workarounds

Extract the target URL before navigation and visit it explicitly:

   cy.origin('https://app2.com', () => {
  cy.get('#dynamicLink')
    .invoke('attr', 'href')
    .then((url) => {
      cy.visit(url)
    })
})

Wait for a post-navigation element instead of asserting on the URL (only works if Cypress stays attached):

cy.get('#dynamicLink').click()
cy.get('[data-expected-after-navigation]', { timeout: 10000 }).should('exist')

Best-effort approach: read the URL after click (not guaranteed if a full reload occurs):

   cy.get('#dynamicLink').click()
cy.window().its('location.href').then((url) => {
  // validate or use the URL
})

Clarification:-

The click itself works correctly. The issue is that Cypress does not detect or reattach to the navigation when it involves dynamic redirects or full page reloads.
