Issue Details

I have a program that uses HTTP Client VIs. The program works properly on Windows, but I receive Error 59 when I run it on my Real-Time Target. How can I fix this issue?


There are a couple of items to check to ensure that your Real-Time Target can use the HTTP Client VIs:
  • Ensure that the target is on the network.
  • Install HTTP Client with SSL Support on the target.
  • Disable any firewalls blocking network communication.
  • If configuring the target with a Static IP, configure your Gateway and DNS Server properly to allow for network communication. This will depend on your network.
  • Also, make sure the correct network routers have the Static IP and Gateway configurations.
