Cannot save pdf file
This has been confused me for a long time. I cannot save the pdf file by simply clicking on the Zotero Connect. In contrast, I can only download the pdf myself and import it into Zotero, which is is too much trouble.

So if you see a red X next to the PDF in the save popup, we'd want to see a Debug ID from Zotero — not the Zotero Connector — for the save attempt. Be sure to reload the page before saving.
Assuming you have access to the PDF on the site itself, the proxy server might not be properly forwarding all aspects of the original request (e.g., cookies), causing the site to return the article page itself instead of the PDF.
I'm able to save from that IEEEXplore page and get a PDF, so it's not any sort of general problem.
