      When the Kiali pod is restarted during the test execution ( e.g. SMCP member is added to the mesh, e.g. when before test hooks reinstall the demo application ) the next UI step in a test always fails on

           CypressError: `cy.visit()` failed trying to load:

https://kiali-istio-system.apps.user-rhos-d-08.servicemesh.rhqeaws.com/console/services?refresh=0

We attempted to make an http request to this URL but the request failed without a response.

We received this error at the network level:

  > Error: ESOCKETTIMEDOUT


      It happens only on OCP 4.16+.
      Maybe the session cookie is being invalidated after Kiali pod is restarted. (IDK)
      It doesn't happen on OCP 4.15.

      I have prepared a simple reproducer for that https://github.com/mkralik3/kiali/commit/d7823c9ca01af98f24db35fb85ed6a2e9abb68ab (see Steps to Reproduce section in JIRA with step-by-step reproducer)
