@Youngin Kim,
Is the issue happening to all computers on your network or only to a specific Linux machine?
Did you install the latest release of Ansys Lumerical on your local Windows computer or Linux machine?
Does the issue happen to ALL simulations? Have you tried running the examples from our website? Ansys Optics Application Gallery (Apps).
What is the error when running the example simulations on our website on a local Windows PC or your Linux machine?
To debug this with your IT, please submit a support request to your Ansys account manager (AM) or your regional representative.
