Issue Details

When I try to create endpoints for my Host Machine and my RT target, my code times out and gives the error message:
Error -6965 CNSErrUnexpectedError. Unexpected error. Please contact National Instruments for support

How can I troubleshoot this issue?


To begin troubleshooting this issue:
  • Try running the LabWindows/CVI example cnsSimple that creates endpoints directly on the host machine to see if the same error occurs
    • If so, follow the steps in this article for a similar type error that occurs when running a similar process in LabVIEW
  • If not, there is likely an issue with how you are configuring your endpoints. Make sure you are specifying them correctly on both systems.
