Why does my task show Blocked because of a DSC?

A task that needs a DSC is set to Blocked when its signatory has no valid DSC that can sign. Record a valid certificate and the task returns to its earlier status.

What you see

The task status changes to Blocked. A comment from the System appears on the task. It starts with Automatically blocked and gives the reason. The people on the task also get a notification.

Why it happens

The task has Requires a DSC to file ticked. The person who signs it has no digital signature that can be used today. The reason in the comment is one of these:

  • There is no DSC on file for the signatory.
  • The application is still in progress. The certificate is not yet issued.
  • The certificate has expired. A certificate that is only close to expiry does not block.
  • The certificate is Encryption-only. It cannot sign a filing, even if its dates look fine.
  • The token is recorded as Lost or Damaged.

How to fix it

  1. Open DSC Management and find the signatory’s record.
  2. Fix the cause. Record the new certificate, or click Renew, or correct the custody entry.
  3. Wait a moment. DueFiler checks again after each change to a DSC.
What you will seeThe task goes back to the status it had before. A comment says it was unblocked because a valid DSC is on file.

Good to know

  • If you set the task to another status yourself, DueFiler blocks it again at the next daily check, until the DSC problem is fixed.
  • A task you blocked yourself, for your own reason, is never changed by DueFiler.
  • A task that is Done is never changed.
  • Portal registration does not block any task.

Cannot see this on your screen?

  • Everyone can use this. If your screen looks different, ask your Admin.
  • DSC Management depends on your firm’s plan. If its menu item shows a small lock, your plan does not include it yet. Ask your Admin.
  • If your firm’s trial has ended, DueFiler is read-only. You can see everything, but you cannot add or change anything.
