Outage in HIN
PDF preview issues in HIN Sign
Resolved MinorIncident Report
We are currently experiencing issues with the display of PDF documents in the preview within HIN Sign.
The issue appears to affect scanned PDFs that use specific compressed image formats (JBIG2 / CCITT Fax) — common in scans from copiers and document management systems.
During the signing process, affected PDF files may appear unreadable or only partially rendered in the preview. The signing functionality itself remains fully operational. At this time, the issue is limited to the PDF preview during the signature workflow.
Our technology partner is already working to resolve the issue.
We apologize for the inconvenience.
