First confirm you are logged in and the link or token has not expired; if it has, re-export the product ZIP from Dev and try a fresh download. Try a different browser and an incognito window, then clear cache and disable any download blockers or antivirus that intercepts ZIPs. Switch networks if you are on a corporate VPN or proxy, since these often block large downloads; ask IT to allowlist the Pega domains and any CDN hosts. If the file is stored in a repository like S3 or Artifactory, the pre-signed URL may be expired or the repo credentials may have changed, so regenerate the URL or refresh credentials. Check file size and try exporting a smaller product first by excluding history or attachments to rule out size limits. If downloading from your Pega app, tail logs while clicking download and verify the stream node is up and has temp directory access, then try another node. Avoid special characters in the product name and repackage if needed. If nothing works, capture the exact timestamp, browser console errors, HTTP status codes, and node logs and share them with your admin to trace the failure end to end.
