    • Error Code: 85440
    Full Message: "Network License Not Available" or "Error 85440: The license link is not available."
    Affected Software: Autodesk products using Network License Manager (NLM) (e.g., AutoCAD, Revit, Inventor, 3ds Max).
    Root Cause Summary: The Autodesk licensing service cannot connect to the license file because the symbolic link (shortcut) to the license file is broken, missing, or inaccessible. | Step | Action | Expected Result |

    If the Autodesk license finder GUI fails, force the link manually:

  • Click OK. The software will test the link.

    • Pro Tip: Always use Port@Hostname (e.g., 2080@lic-svr). This tells the client exactly which port and server to talk to, bypassing broadcast issues.

    Error 85440 is a critical license acquisition failure in Autodesk products (e.g., AutoCAD, Revit, Inventor) using Network License Manager (NLM). The error explicitly indicates that the client application cannot retrieve a license from the designated license server. The diagnostic link: parameter in error logs helps administrators isolate the failure point between the client and the server.
