Add documents from the sciencedirect web page, there is no author information in zotero. In addition, the verification pop-up window for downloading pdf from sciencedirect also disappeared.

    The verification popup (CAPTCHA) is only for PDF downloads. It doesn't apply here.

    But you likely are being blocked/rate-limited by Elsevier, just for the metadata in this case.

    Have you been trying to save a large number of items? This could also be due to your geographical location, or some combination of the two.

    Can you provide a Debug ID for reloading the page and reproducing this?

    A phenomenon worthy of attention is that the same problem occurs in edge and chrome browsers, but it is normal in firefox and there is no problem.

    Sorry, in this case we need a Debug ID from the Zotero Connector, not from Zotero.

    We only ever want a Debug IDs, not raw output.

    But yes, the metadata request is getting blocked by ScienceDirect.

    You didn't answer my question: have you been trying to save a large number of items? If you have, it could easily work (for a while) in a new browser where you haven't done so, or just in a browser where you've accessed a different array of sites.
  • novwyz
    I only saved 5 documents (using edge browser), and the chrome browser was newly installed today.
    The equally commonly used Firefox browser does not have this problem.
  • dstillman
    What happens if you just click on the above link on this page?

    You can try clearing cookies and/or trying from a different network. You're being blocked by ScienceDirect's anti-bot protection. Unless you're saving multiple items via Zotero, in which case the rate of requests could be an issue, this is unfortunately out of our control.
  • novwyz
    thx
  • dstillman
    You didn't answer my question, though. What happens if you click the above link? Does Zotero offer to import the file, or do you get an error (or CAPTCHA) from ScienceDirect?

    Hello,When the above link is opened, the "Are You A Robot?" page will be displayed, and the RIS file will be downloaded after verification.

    I asked many colleagues and it seems that the school’s IP address is restricted. When I connect to the mobile hotspot, it's completely normal.

    Right, it's just the same thing I say above — ScienceDirect's anti-bot protections. You can see whether after trying to download a RIS file manually and completing the CAPTCHA you're able to continue using Zotero for a while.

    If your school has a single outgoing IP address, that could certainly result in erroneous blocking. Or their systems may just allow a much lower rate limit from your geographical location.
  • novwyz
    After I verified and downloaded ris, other documents still cannot be used. This should be due to the IP.
  • dstillman
    If you go to Cite → "Export citation to RIS" on the ScienceDirect page, do you get a CAPTCHA ("Are You A Robot?") each time? Or does it start working for a while after you do it once?
  • novwyz
    No, CAPTCHA appears when opening sciencedirect. When clicking "Export citation to RIS", the CAPTCHA will not appear and RIS can be downloaded.
    It can work for a period of time after verification once.
  • dstillman
    But you're seeing the CAPTCHA occasionally just when browsing ScienceDirect when not using Zotero at all?
  • novwyz
    yea
  • dstillman
    OK, thanks.
