@almaes This issue can happen because of cached data, an outdated version of the SAP Concur mobile app, or if the device is connected to the internet via some specific VPN and this VPN replaces the root certificate.
The most effective way to resolve the error message is to clear the app's cache > uninstall the app > download it again, and also disconnect from any VPN that the mobile device might be connected to.
To clear the cache, uninstall, and download the mobile app again, please follow the steps below:
1. Open the SAP Concur mobile application,
2. Tap Done (iOS) or X (Android) in the upper left corner,
3. Double tap with two fingers on the SAP Concur Logo to enter the settings menu,
4. Go to System > Clear Cache,
5. Delete the SAP Concur app from the phone,
6. Restart the phone,
7. After the restart, reinstall the SAP Concur app.
Before trying to log in again, make sure to also disconnect from any VPN that the mobile device might be connected to.
