Check certificate validity first
Reinstalling an application does not restore an expired certificate. Start with the renewal route if validity is the issue. A working application and a valid certificate are separate checks.
Separate the application from the portal
Note whether the issue happens at launch, authorisation, certificate selection, signing or document submission. This helps direct diagnosis to the right stage.
Card and reader problems
Check the device connection and whether the application detects the card. Stop guessing if there is an access-code issue. Do not send the code in a message or form.
