During testing session using viewport navigation to different pages the page weren't loaded

[claudiamenezeskk]

I have the code below that I need to do a login and navigate to a viewport to test the responsive elements simulating the iPhone device, the login happens without any problem but when a need to navigate to the page that I need to interact to, the page is loaded empty.

In the meantime I have an error in my console: 'Refused to apply style from 'https://localhost:8080/mcc-static/styles.7b4b95b66d9e1a9a44c4.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

But we haven't any problem-related in a real application duo to access this css.

At the first executions I have no problem, when it's is stressed this problem happens.

Cypress.Commands.add('visitMobile', (url, viewport) => {
    cy.viewport(viewport);
    cy.visit({
        url: url,
        headers: {
            'user-agent': Cypress.config('userAgentMobile')
        }
