Actually, there appears to be ongoing Denial of Service issues on the NIST Site causing intermittent 503 errors.  If you retry the update manually a few times it should go through.  I presume NIST is working to address the root cause of issues seen on their site.

And "please ensure that you or the tools you use have the latest schema files, which were recently updated" , are we updated ?

Hi Craig, I am having this issue with CVE subscription. In the web interface, I get a success return, but in the loader-messages.log I get the following (one of the entries in a full run as I tried to recreate the subscription after the fails):-

Error downloading CVE data for URL https://services.nvd.nist.gov//rest/json/cves/2.0/?lastModStartDate=2024-07-02T12:00:00Z&lastModEndDate=2024-10-30T12:00:00Z&noRejected&resultsPerPage=1&startIndex=0

I've tried lots of times, even registered for an API key but still no joy. I see mention of a schema file, do I need to download and make that available on the zenworks primary in question?

Running 23.4

I get this on a fresh install in a test environment too, same version. I can download content using wget from the nist site on the zenworks server.
