Why is Cypress getting stuck on authorize/resume?

Help

I have a simple cypress script I am trying to use to log in…

const fillLogin = async () => {
  cy.log("Filling login");
  cy.get("#username")
    .should("be.visible")
    .type("demouser@purepm.co");
  cy.get("#password")
    .should("be.visible")
    .type("TestPassword0!");
  cy.get("button[name=\"action\"]")
    .should("be.visible")
    .click();
  return cy.get(".main-container")
    .should("be.visible");
};

On a normal browser everything works fine but using cypress it just gets stuck at https://me.us.auth0.com/authorize/resume?state=... and never redirects back to callback like it is supposed to. Any ideas?
