if you use SSO/OIDC, set the Auth Service to issue a new refresh token on each renewal and turn off “Set refresh token expiry from IdP session expiry”; short IdP lifetimes are the most common cause of sudden logouts.  Next, double-check both places where inactivity can be enforced: Access Group’s Authentication timeout and the Constellation inactivity timeout feature; configure them intentionally or disable as needed. Also review platform timeouts set via DSS/prconfig especially prconfig/timeout/browser/default and timeout/application—and raise them or remove accidental overrides.  Make sure your load balancer is sticky and JSESSIONID isn’t bouncing between nodes; lack of stickiness = instant logout. Check cookies in the browser dev tools to confirm Pega-RULES/JSESSIONID are present and not blocked by settings, extensions, or SameSite rules.  If you still see drops, look for token-refresh or CORS errors in the network tab and verify passivation or node restarts aren’t terminating sessions.  Finally, this exact symptom is being discussed for 24.2.x; align your settings with the above and retest
