  • Measurement and Automation Explorer (MAX)

Issue Details

  • I'm having problems retrieving the settings for my remote target when trying to access it through NI Measurement and Automation Explorer (NI MAX) or the NI Network Browser.
  • Whenever I try to connect to a Remote Target in NI MAX, I see the following error:
There was a problem contacting the System Web Server on the target.


Follow these steps to resolve the issue:
  1. Make sure the remote target is connected and running.
    • If the target has DIP switches, ensure all are on the OFF position. 
  2. Check that the minimum software required by the hardware is installed on the host PC. Verify that the software versions installed are compatible with the OS.
  3. Verify that TCP Port 3580 is not being blocked by a firewall.
    • This port is needed to communicate with remote targets.
  4. Verify that the NI System Web Server service is running.
    • Navigate to Start>>Run, and type in services.msc.
    • Navigate to NI System Web Server, and check if the service is stopped. If so, manually restart the service by right clicking on the service and hitting 'Start'.
  5. Reboot the host machine.
  6. Try reinstalling Measurement & Automation Explorer.
  7. If using a proxy server, ensure that is it not in the host PC's Environment Variables. Work with your IT carefully to try and delete the Proxy Variables, if there are any. Note: Be careful, as deleting some other Environment Variables can result in damaging some other applications on your PC which can in turn result in damaging and/or crashing of your PC.
If the steps above do not resolve the issue, gather a Technical Support report from NI MAX for the local machine. To obtain this report, follow the steps in Using MAX Technical Report to Document Configuration Information. Once obtained, please contact National Instruments Support.

Additional Information

If the NI System Web Server is stopped, other services may also be. Check and if required, start the NI PXI Resource Manager and the NI LXI Discovery Service.
