Before "fdtd.run() "

you should be able to see the FDTD file, and save it to a fsp file on you local machine. Then directly run it on your local computer, and then move to the cluster and run it. If the cluster has GUI you can open and run the file. If not, please refer to this link: https://optics.ansys.com/hc/en-us/articles/360024974033-Running-simulations-using-terminal-on-Linux 

You can also use one of the online examples with port objects, such as this one  https://api.lumerical.com/app-gallery/fetch-download-web?id=c118296f-waveguide-crossing 

run the example file on the cluster and try to get the result. See what happens.
