    • License validation failed or expired: The software couldn't confirm a valid license with the licensing service.
    • Network or server issue: Connection problems to Autodesk’s licensing servers or to your company’s network license server.
    • Corrupt or mismatched licensing files: Local licensing components or cached license files are damaged or inconsistent.

    • Concurrent-license limits reached: For network (floating) licenses, all available seats may be in use.

    The license server expects a response within milliseconds.

The server marks the request as "Hot" because it hasn't timed out yet, but it isn't succeeding either. autodesk license status 2100 hot
