Issue Details

I receive the following communication error when installing, updating or upgrading a product from within NI Package Manager (NIPM).

There was a problem updating the feeds cache.
Failed to update all fields.
Visit ni.com/info and enter the Info Code NIPMCommError for more information.
Additional error information:
An error occurred while trying to download the feed:
http://download.ni.com/support/nipkg/products/ni-package-manager/released/Packages.gz
The network is down, unreachable, or has been reset. (Could not resolve host: download.ni.com)


Solution

Here are some of the reasons why you encounter this error and the corresponding solutions:
  1. You are using Direct Access, and you are on an IPv6 only network. You will experience networking issues, and can't install any products from NI Package Manager if you are on an IPv6 only network.
  2. You can't access any of NI URLs due to some networking issues. If you can't access any of the below URLs using Telnet or another tool, you need to contact your IT department to make sure the corresponding ports are open.
    • download.ni.com  on port 80
    • conduit-locator.ni.com on port 443
    • conduit.ni.com on port 443
  3. Your proxy (though Internet Options in Windows) is not set up correctly. If you are behind a proxy server, make sure to use http proxy servers. Otherwise you can use the following workaround:
    • Open %localappdata%\National Instruments\NI Package Manager\nipkg.ini
    • Fill out the proxyserver= <field> with your proxy information. The field format usually is host:port but you can ask your IT department to confirm.
  4. Your system doesn't trust NI's https certificates. You should contact your IT department to confirm the certificate settings.
  5. Make sure you are not using a VPN, as this can also affect or block the installation.
  6. Try a different network. Sometimes networks have other limitations that can prevent NI Package Manager from working properly. Try another network, such as your home network or using your phone as a wifi hotspot.
