503 Error when converting pdf using aspose

Aspose.PDF Product Family
1

Hi Team,

We are encountering a 503 Service Temporarily Unavailable error while converting documents to PDF through the Aspose integration.

Issue Description

  • The conversion process starts successfully.
  • Our custom logs are printed before the conversion request.
  • The failure occurs when AsposeClientImpl invokes the Aspose conversion service.

Error Log

Conversion in progress for document: <document-id>

Aspose current version = 26.4.0

Failed to convert to PDF:
503 Service Temporarily Unavailable

org.nuxeo.ecm.core.convert.api.ConversionException:
java.io.IOException: Failed to convert to PDF

Recent Changes

The only recent changes made were the addition of logging statements for tracing the PDF conversion flow. No conversion logic, request payload, or Aspose integration code was modified.

Request

Could you please help verify:

  1. Whether the Aspose conversion service is currently available and healthy.
  2. Whether there are any recent outages or deployments affecting the service.
  3. Whether any endpoint, proxy, or load balancer is returning HTTP 503.
  4. If server-side logs are available for the failed conversion request.
