After logging in and working actively for a few minutes in the New User Experience (UI/UX), the session times out and you have to re-authenticate.
This is caused by the application not gently handling a network disconnect.
It is not actually related to SSO, except that it will redirect you to the SSO Error URL
A temporary loss of the network connection logs out a user of the Modern UX. This does not happen within the Classic UI.
STEPS TO REPRODUCE:
Expected Results: The application provides a message to the user to check their connection and try again.
Actual Results: The user is logged out of the UI with no explanation, or a chance to try again.
Release : 15.8.1, 15.9, 15.9.1
Component : CA PPM SAAS OPERATIONS SSO
GCP environment using Okta and SSO Authentication
Defect DE60301
Will be fixed post 15.9.2
Workaround: Click the button Back on the browser once connection is restored.
