It seems that HP has changed URL of website to check warranty of their product.
There is such message when you enter old website:
"You are on HP Support Center for products such as printers, tablets, and desktops.
For products such as servers, storage, and networking, go to HP Support Center - Hewlett Packard Enterprise . "
So HP warranty poll ends currently with error.
When you place attached config file into directory c:\Program Files (x86)\SolarWinds\Orion\AssetInventory\
and restart Orion services, it should be able poll HP warranty again.
Hope it helps.
