Issue Details

  • ​​​​​​I receive one of the following errors when I try to connect to the Compile Cloud Service:
    • Error 363507 - LabVIEW: LabVIEW could not verify the authenticity of the server.

  • Error -123011 - NI-Farm: Farm server is not responding. Be sure the specified hostname is correct, the server is running and configured to accept remote requests. 
  • I cannot connect to the server using the Test Connection button in Configure dialog.
  • 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.


To resolve the errors, follow the next steps:

1. Verify Account Details
  • Make sure your username and password are correct.
  • See if you can log into your NI Cloud Portal account.
  • Make sure you have LabVIEW FPGA Compile Cloud Service as an active product under your account.
If you do not have LabVIEW FPGA Compile Cloud Service as a product under your account, you can sign up for it on the NI LabVIEW FPGA Compile Cloud Service page.
2. Check Internet/Firewall Settings
  • If this behaviour occurs during compilation, you may have temporarily disconnected from the internet. Right-clicking on the FPGA build spec in the project tree and selecting Reconnect to Compilation to continue from where the compilation was disconnected.
  • Check firewall and make sure port 443 (HTTPS) is open. 
  • Navigate to in your web browser and make sure you can see a white page with the words "It works!" on the page.

  • This tests the most basic connection to the server farm, if this 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 exceptions depending on the alias name and *
    • For specific IP address exceptions, you need to allow exceptions for the range: -
    • Using proxifier software that forces communication to/from LabVIEW and other NI software through a proxy is another possible solution.
  • If your application use 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 needs to have the Xilinx Compile Tools installed. Although the compile farm may be the same computer you are working on, you still need those ports open to communicate. 
3. Check Security Software for Cloud-Based Applications Settings
Some companies use security software that is specially designed to protect again threats in cloud-based applications, like the NI LabVIEW FPGA Compile Cloud Service. If your company uses this kind of security software, we recommend working with your IT department to determine if the security software is blocking the NI Cloud services.

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.

Sometimes it's also helpful, even if we already have an account, re-create the same account with the same email from scratch.

If you're unable to access the NI LabVIEW FPGA Compile Cloud Service after following these troubleshooting steps then you can set up a local compile server instead. Information on how to do this can be found on Getting Started with the LabVIEW FPGA Compile Farm Toolkit.
