Connector Communication Error: saveAttachmentFromResolver failed on IEEE Xplore

huangyyuan2005
Hello Zotero Team,

I am using Zotero 10.0.8 (64-bit) with Zotero Connector on Edge. I am connected directly to my university campus network without any proxy, and I have full institutional access to IEEE Xplore.

My classmates can successfully save IEEE PDFs via Zotero Connector, but it fails on my device. When saving items from IEEE, I receive these errors:
Method saveAttachmentFromResolver failed
Method saveSingleFile failed
Could not establish connection. Receiving end does not exist.

I have submitted the debug report with Report ID: 738089745.

I have tried restarting Zotero, restarting the browser, and disabling Windows automatic proxy detection. Manual PDF download via browser works fine. Could you help check whether this is a local issue or a known translator/connector bug for IEEE?

Thank you!

    Submit a Debug ID from Zotero for an attempt to save that fails.

    Here are the Debug IDs for a failed save attempt on IEEE Xplore:

    Zotero Desktop Debug ID: D1691099185

    Zotero Connector (Edge) Debug ID: D1319085582

    Just to clarify, I am connected directly to the campus network without any proxy or special browser tools. Manual PDF downloads work perfectly fine in the same browser, but the Zotero Connector fails to save.

    Please let me know if you need anything else or if you find out what is causing the issue.

    You should disable other extensions (ModHeader is likely to cause interference) and try again, or try in a new Edge profile.

    Quick update! It turned out NOT to be an extension issue. Even with a clean Edge profile, it still failed.

    The real culprit was the NS_ERROR_FILE_IS_LOCKED error in the logs. My laptop's pre-installed security software (it has a "File Download Protection" feature) was locking the temporary files Zotero tried to move. After I disabled that protection and moved the Zotero data directory, everything works perfectly now!

    Thanks again for your guidance with the debug logs. Hope this helps other users facing the same local environment issue!
