How to Fix “Issue while validating digital signature: Digital Signature ID is Not Valid for the Uploaded Document” in ICEGATE
Complete Guide to Update DSC in ICEGATE Portal
If you are trying to upload a digitally signed PDF on the ICEGATE portal and receiving the error:
“Issue while validating digital signature: Digital Signature ID is not valid for the uploaded document”
don’t worry. This is one of the most common Digital Signature Certificate (DSC) errors faced by ICEGATE users.
In this guide, we will explain why this error occurs and how to update your DSC in ICEGATE to resolve the issue permanently.
Why Does This Error Occur?
The error usually appears when:
- You have signed the PDF using a valid Digital Signature Certificate (DSC).
- However, the same DSC is not registered or updated in your ICEGATE profile.
- You recently renewed your DSC and are still using an old DSC registered in ICEGATE.
- Your DSC token has changed, but the profile has not been updated accordingly.
In simple words, the Digital Signature used to sign the document and the Digital Signature registered in ICEGATE do not match.
As a result, ICEGATE cannot validate the uploaded document and displays the error:
“Digital Signature ID is not valid for the uploaded document.”
