Hi Wangning,

Thank you for your question and for sharing your files. I have received them and will take a look. Could you please tell me which version of Lumerical you are using? 

I was able to replicate your error in 2023 R1. I believe the error is indicating some kind of API connection issue, but I am not sure exactly what is causing it yet.

Best,

Anna
