LabVIEW FPGA Compile Cloud Connection Issues

  • LabVIEW FPGA Compile Cloud Service

Issue Details

  • I want to use FPGA cloud service for development, so I tried to connect to the server using the Test Connection button in Configure dialog. Because I am behind a Proxy/Firewall system, I expected to get a Proxy connection dialog (as I get one when registering NI software) but it never comes up, and naturally the test failed to contact the server.
  • I cannot connect to LabVIEW FPGA Cloud Compile Service through my corporate network/domain but I can if I use my home network or cellphone hotspot.
  • I receive either of the following errors when I try to connect to the Compile Cloud Service:
    • LabVIEW: LabVIEW could not verify the authenticity of the server.
    • An error occurred attempting to connect to this compile server.
      Details: NI-Farm: Farm server is not responding. Be sure the specified hostname is correct, the server is running and configured to accept remote requests. 


  • Make sure your username and password are correct.
  • Make sure you have LabVIEW FPGA Compile Cloud Service as an active product under your account
  • Check firewall and make sure port 443 (HTTPS) is open. 
  • Navigate to in your web browser and make sure you see a white page with the words It works! on the page. This tests the most basic connection to the server farm, if it fails to load then proceed to check the following firewall exceptions. 
  • Check to see if your network traffic passes through a proxy.  NI LabVIEW FPGA Compile Cloud Service cannot always be reached through a proxy -- it will try to connect directly to the computer.
    • IT can make exception dependent on the alias name and *
    • For specific IP address exceptions, you need to allow exception for range: -
    • You might be able to solve using proxifier software that forces communication to/from LabVIEW and other NI software through a proxy.

Additional Information

Proxy exception set up for specific IP address will not work for NI LabVIEW FPGA Compile Cloud Service, because the IP addresses change as the server loads are balanced.

In order to use the Xilinx IP functions, port 3580 and 3582 need to be open to communicate with the FPGA compile farm server, which is needed to be able to configure those Xilinx IP functions. Additionally, the computer using these IP functions will need to have the Xilinx Compile Tools installed. Although the compile farm may be the same computer as what we are working on, we will still need those ports open to communicate.
