I have a grouping of Cypress tests that are failing, *only in my Jenkins environment*. An entire `describe` block is failing to find an element. Every test in the block starts with the same commands:

```js
describe("This section of tests", () => {
  it("Test for something in this section", () => {
    cy.login(); // custom login command, works in all other test blocks
    setupPage(); // page setup function, no problems in all other test blocks
    cy.wait(10000); // desperation wait

    cy.get("#toggle-detail-pane-button").click(); // issue here!
    // all tests in block run more assertions and commands after this
  });

  // more similar tests in block
});

// more describe blocks that also use cy.login and setupPage, with no issue

```

When I run these tests in the cypress test UI, they all pass. When I run them in the terminal on my machine with `npx cypress run`, they pass. When I ssh into a remote OpenStack terminal which is set up to run my project and run cypress, and run `npx cypress run`, they pass.

When I run the tests in Jenkins, which uses a handful of identical OpenStack instances to run cypress in parallel, the tests fail, consistently, with the following message:

```
AssertionError: Timed out retrying after 4000ms: Expected to find element: `#toggle-detail-pane-button`, but never found it.

      at Context.eval (http://localhost:3000/__cypress/tests?p=cypress/integration/stuff/mytests.spec.js:519:8)

```

I have tried reorganizing my tests, rewriting them, etc, but no luck. I cannot figure out what is going wrong here. My Jenkins environment uses a custom [sorry-cypress](https://github.com/sorry-cypress/sorry-cypress) setup, and for some reason, the dashboard is not registering the tests, so I can't go and view any screenshots or videos (that is a whole separate can-of-worms problem).

Why would only these tests fail only in my CI/CD env? How can I even begin to debug this?

### Edit: screenshots

I was able to rerun the CI/CD with screenshots and videos, and then I was able to `scp` the files off of the instance with the failing tests. When running on my machine, cypress has no problem finding the element:

When using the cypress selector playground on my machine, it finds it as well:

But in the screenshot I pulled off of the openstack instance running exactly the same test, it can't find it:

(Sorry for all the green, this is a proprietary app)

What gives?
