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?

1. Close the Authentication stale request error window and try logging in again. If this doesn't work, continue with step 2.
2. Clear browser cache and cookies (Safari → Settings → Clear History and Website Data).
3. Close all tabs and start a fresh browser session.
4. Ensure cookies are allowed in Safari (Settings → Safari → Privacy & Security).
5. Remove any saved Shibboleth URLs or credentials from browser/app settings.
6. Avoid using the Back button or old bookmarks—navigate directly to the resource.
7. If on Wi-Fi, try switching to cellular data or using a VPN if network issues persist.

What if the error keeps happening?

• Try a different browser (e.g., Chrome or Firefox).
• Restart your device.
