Cause

Whois response is providing no answer back when we request the information on port 43 via TCP.

Resolution

  1. Navigate to Orion/Admin/AdvancedConfiguration/Global.aspx.
  2. Turn on IsTwoPhaseEnabled.
  3. If this does not work, install any third party Whois lookup tool on the SolarWinds server to validate a response is made. (For more information, see Troubleshoot Missing BGP/Whois/Contact Information)
  4.  Run Wireshark and filtered tcp.port == 43.
  5. Start WhoIS tool to see if query provides a response. We should see an answer in the Wireshark provided instantly. 
  6. If no answer is provided then check with the Firewall team to investigate.
Note: Some requests will be redirected to those servers depending on which region the IP range belongs to. Please make sure the *tcp:43* traffic is allowed to the following regional servers as well: North American: whois.arin.net Europe: whois.ripe.net Latin America: whois.lacnic.net African: whois.afrinic.net Asia-Pacific: whois.apnic.net
