Shibboleth Stale Request Login Error

What does the "Stale Request" or "Stale Login" error mean?

This error occurs when the login session has expired or become invalid. Common causes include:

  • Using the Back button after login.
  • Bookmarking the login page instead of the resource.
  • Session timeout or cached credentials

Why does this happen more often on iOS/macOS?

Apple devices sometimes block cookies or retain stale session data in Safari or in-app browsers. Additionally:

  • Safari's privacy settings may prevent cookies.
  • Multiple tabs or saved credentials can interfere with logins.
  • Network changes (e.g., switching from Wi-Fi to cellular) can affect login sessions.

How do I fix it?

It may take several tries to successfully login. Close the stale request error window and try logging in again.

When using iOS, choose the option to use FaceID, or TouchID on MacOS after you successfully login the first time.

  1. Confirm Face ID is set up on your device by going to Settings > Face ID & Passcode. Make sure Face ID is enabled and your face is enrolled.
  2. Open the UKG Timekeeping App on your iPhone.
  3. Log In with your access.caltech credentials.
  4. Tap the Menu (☰) or Profile icon and select Settings.
  5. Find the option for Biometric Login or Face ID.
  6. Toggle it ON and grant permission
  7. When prompted, allow UKG to use Face ID and confirm through the iOS pop-up.

If using MacOS, try the following:

  • Switch to Chrome or Firefox browsers for Timekeeping UKG.
  • If using Safari, clear cache and cookies (Safari → Settings → Clear History and Website Data).
  • Close all tabs and start a fresh browser session.
  • Ensure cookies are allowed in Safari (Settings → Safari → Privacy & Security).
  • Remove any saved Shibboleth URLs or credentials from browser/app settings.
  • Avoid using the Back button or old bookmarks—navigate directly to the resource.
  • If on Wi-Fi, try switching to cellular data or using a VPN if network issues persist.
  • Restart your device.
