Connector Rejected with status "0" 843496539

jeanggi90 · September 25, 2025

I am having an issue storing PDFs from amd.com using the connector app. The error I get looks as follows:

```
[JavaScript Error: "HTTP request to https://www.amd.com/content/dam/amd/en/documents/epyc-technical-docs/programmer-references/58088.pdf rejected with status 0"]
```

PDFs from other sites work as expected. So the issue is not the connection to the Zotero app, but it seems to fail to retreiv the PDF.

Many thanks

How are you saving the PDF? Could you post a Connector Debug ID for the attempted save?

I open the URL to the pdf in the browser (e.g. the one above). Click on the "Save to Zotero (PDF)" button of the connector. And then the button turns into a red crossmark saying "Saving failed. Is Zotero running?". Obviously, Zotero is running and storing other pdfs works fine.

Zotero Debug ID: D1256457167
Connector Debug ID: D717864258

(Both were gathered in seperate runs!)

Does it work in a new Firefox profile?

Yes, it indeed does. What it the issue? Why does it not work for only some PDFs?

Does your main Firefox profile use stricter security settings than the default? If so, could you try relaxing some of them and seeing if it starts working with your main profile and lets us know which setting is causing the issue?
