This guide provides technical protocols for identifying, diagnosing, and resolving the most frequent operational challenges encountered within the IUSign Enterprise platform.


Prerequisites

  • Successful authentication into the IUSign portal.
  • Understanding of standard web technologies (Cookies, Cache, SMTP, PDF).

Strategic Overview

Maintaining the integrity and velocity of digital document transactions requires a proactive approach to troubleshooting. While the IUSign platform is engineered for high reliability, external factors—such as browser configurations, mail server security policies, and network instability—can occasionally interrupt the document lifecycle. This guide provides a structured framework for incident resolution, moving from local client-side diagnostics to advanced administrative remediation.


1. Recipient Engagement and Delivery Failures

Why hasn't my recipient received their invitation?

The most common cause of non-delivery is local SMTP filtering or syntax errors.

  • Syntax Check: Verify that the recipient's email address is spelled correctly in the Envelope Detail Panel.
  • SMTP Bounces: Review the Failure Log for 5xx/4xx error codes returned by the recipient's mail server.
  • Spam Mitigation: Advise the recipient to whitelist the iusign.com domain. For enterprise organizations, ensure SPF and DKIM are correctly configured.

The signing link says "Invalid" or "Expired."

  • Temporal Expiry: The sender may have set a specific Expiration Date that has passed.
  • Revocation: The envelope may have been Voided or Corrected, which invalidates previous tokens.
  • Single-Use Logic: In some high-security configurations, tokens are invalidated after a successful submission.

2. Document Rendering and Performance

The document is loading slowly or appearing blurry.

  • Asset Complexity: High-resolution images or hundreds of pages can increase rendering time. Utilize PDF optimization tools to reduce file size before ingestion.
  • Browser Resources: Close background browser tabs or applications to free up system memory for the SVG/Canvas renderer.
  • Font Embedding: If text appears garbled, ensure all fonts are fully embedded in the source PDF asset.

I cannot find the "Finish" button after signing.

  • Guided Navigation: The IUSign portal will block finalization until every Mandatory Field is executed. Use the "Next" button to find any missed requirements (often small checkboxes or initial fields).
  • Validation Errors: Ensure that data entered into text fields (Emails, Dates) matches the required validation patterns.

3. Account and Administrative Governance

I've lost access to my Multi-Factor Authentication (MFA) device.

  • Recovery Codes: Utilize the emergency recovery codes generated during the MFA Setup.
  • Admin Intervention: If recovery codes are unavailable, contact your organizational Tenant Admin, who can reset your MFA status after verifying your identity.

"Access Denied" on Administrative Modules.

  • Role Mapping: Your current role may not have the necessary permissions. Verify with your Tenant Owner that you are assigned the Admin or Owner role.
  • Session Persistence: If your role was recently changed, log out and re-authenticate to refresh your session's permission manifest.
