Problem

If you're unable to download files from neoCatalog while using Google Chrome, it's likely due to Chrome's security policy blocking mixed content — secure (HTTPS) pages attempting to download insecure (HTTP) files.


Starting with Chrome 81, downloads over HTTP are blocked if initiated from HTTPS pages, as explained by Google https://blog.chromium.org/2020/02/protecting-users-from-insecure.html



Solution: Allow Insecure Content for neoCatalog

You can temporarily adjust browser settings to enable the download:

  1. Open neoCatalog in Chrome.
  2. In the URL bar, enter chrome://flags/#treat-unsafe-downloads-as-active-content. 
  3. Scroll to “Available”.
  4. Set it to “Enabled”.
  5. Refresh the page.


Alternative: Use a Different Browser

If the issue persists or you prefer not to modify Chrome settings, try using:

  • Firefox

  • Microsoft Edge
